Nuclear pores are protein complexes that punctuate the nuclear envelope that surrounds the cell nucleus. The pores facilitate the two way transport of molecules including RNA and ribosomes et al at up to 1000 times per second per pore. Whilst some molecules may simply diffuse, other require enabling, via an active process called the RAN cycle, by specialist protein structures called nucleoporins.

gp210 (C-terminal) Antibody- Rabbit Anti-gp210 (C-terminal)
The nuclear pore complex is a massive structure that extends across the nuclear envelope, forming a gateway that regulates the flow of macromolecules between the nucleus and the cytoplasm. Nucleoporins are the main components of the nuclear pore complex in eukaryotic cells. GP210 is a membrane-spanning glycoprotein that is a major component of the nuclear pore complex, it is an evolutionarily conserved and has early roles in nuclear pore formation and mediates pore dilation with its tail-binding partners

Karyopherin alpha2 (KPNA2) Antibody- Rat Anti-Karyopherin alpha2 (KPNA2)
The import of proteins into the nucleus is a process that involves at least 2 steps The first is an energy independent docking of the protein to the nuclear envelope and the second is an energy dependent translocation through the nuclear pore complex Imported proteins require a nuclear localization sequence (NLS) which generally consists of a short region of basic amino acids or 2 such regions spaced about 10 amino acids apart Proteins involved in the first step of nuclear import have been identified in different systems These include the Xenopus protein importin and its yeast homolog SRP1 (a suppressor of certain temperature sensitive mutations of RNA polymerase I in Saccharomyces cerevisiae) which bind to the NLS KPNA2 protein interacts with the NLSs of DNA helicase Q1 and SV40 T antigen and may be involved in the nuclear transport of proteins KPNA2 also may play a role in V(D)J recombination

Mad1p Antibody- Rabbit Anti-Mad1p
MAD1 is a non-essential gene that encodes a component of the spindle checkpoint. The spindle checkpoint delays the onset of anaphase in cells with defects in mitotic spindle assembly or in the attachment of chromosomes to the spindle microtubules. The checkpoint works by inhibiting the activity of the anaphase promoting complex, thereby preventing the degradation of several cell cycle regulators. Like other spindle checkpoint mutants, MAD1 loss-of-function mutants are sensitive to benomyl and cannot delay cell division in response to spindle depolymerization. Mad1p becomes hyperphosphorylated upon spindle depolymerization

Mad2L1 Antibody- Mouse Anti-Mad2L1
Mad2L1 is required for the execution of the mitotic checkpoint which monitors the process of kinetochore spindle attachment and delays the onset of anaphase when this process is not complete It inhibits the activity of the anaphase promoting complex by sequestering CDC20 until all chromosomes are aligned at the metaphase plate

Nup153 Antibody- Sheep Anti-Nup153
Nuclear pore complexes are extremely elaborate structures that mediate the regulated movement of macromolecules between the nucleus and cytoplasm These complexes are composed of at least 100 different polypeptide subunits many of which belong to the nucleoporin family Nucleoporins are pore complex specific glycoproteins characterized by cytoplasmically oriented O linked N acetylglucosamine residues and numerous repeats of the pentapeptide sequence XFXFG Nup153 has three distinct domains a N terminal region within which a pore targeting domain has been identified a central region containing multiple zinc finger motifs and a C terminal region containing multiple XFXFG repeats Nup153 is a possible DNA binding subunit of the nuclear pore complex (NPC) The repeat containing domain may be involved in anchoring components of the pore complex to the pore membrane

Nup53 Antibody- Rabbit Anti-Nup53
Nup53 encodes a recently identified nuclear pore protein. Transport of macromolecules between the nucleus and the cytoplasm of eukaryotic cells occurs through the nuclear pore complex (NPC), a large macromolecular complex that spans the nuclear envelope. The yeast NPC shares several features with the vertebrate NPC, despite being smaller and less elaborate. Nup53p forms a complex with two other nucleoporins, Nup170p and Asm4p. The complex is found on both the nuclear and cytoplasmic faces of the NPC, and associates with Pse1p, a member of a protein family implicated in nuclear protein import, via direct interaction between Nup53p and Pse1p. Nup53p is structurally similar to Asm4p, and similar proteins sequences are found in several eukaryotes including human and other multicellular species. Nup53p is not essential; deletion of Nup53 and ASM4 causes slow growth and altered subcellular distribution of Pse1p. In a nup53 pse1 double mutant, NLS-containing proteins are mislocalized to the cytoplasm

Ran Antibody- Rabbit Anti-Ran
Ran (ras-related nuclear protein) is a small GTP binding protein belonging to the RAS superfamily that is essential for the translocation of RNA and proteins through the nuclear pore complex. The Ran protein is also involved in control of DNA synthesis and cell cycle progression. Nuclear localization of Ran requires the presence of regulator of chromosome condensation 1 (RCC1). Mutations in Ran disrupt DNA synthesis. Because of its many functions, it is likely that Ran interacts with several other proteins. Ran regulates formation and organization of the microtubule network independently of its role in the nucleus-cytosol exchange of macromolecules. Ran could be a key signaling molecule regulating microtubule polymerization during mitosis. RCC1 generates a high local concentration of Ran-GTP around chromatin which, in turn, induces the local nucleation of microtubules. Ran is an androgen receptor (AR) coactivator that binds differentially with different lengths of polyglutamine within the androgen receptor. Polyglutamine repeat expansion in the AR is linked to Kennedy's disease (X-linked spinal and bulbar muscular atrophy). Ran coactivation of the AR diminishes with polyglutamine expansion within the AR, and this weak coactivation may lead to partial androgen insensitivity during the development of Kennedy's disease.

RanGAP Antibody- Rabbit Anti-RanGAP
Ran is a small signaling GTPase that is involved in nucleocytoplasmic
transport. Two additional functions of animal Ran in the formation of spindle
asters and the reassembly of the nuclear envelope in mitotic cells have been
recently reported. In contrast to Ras or Rho, Ran is not associated with
membranes. Instead, the spatial sequestering of its accessory proteins, the Ran
GTPase-activating protein RanGAP and the nucleotide exchange factor RCC1,
appears to define the local concentration of RanGTP vs. RanGDP involved in
signaling. Mammalian RanGAP is bound to the nuclear pore by a mechanism
involving the attachment of small ubiquitin-related modifier protein (SUMO)
to its C terminus and the subsequent binding of the SUMOylated domain to the
nucleoporin Nup358
