Cell division is the key biological process called mitosis whereby a parent cell divides into two or more daughter cells. Cell division is focused on the preservation of the originating cells genome thus cell information contained in chromosomes must be replicated.
Mitosis proceeds on well regulated staged cellular pathways, part of the cell cycle. These are the interphase, prophase, premetaphase, metaphase anaphase and finally telophase.
A special type of cell division is meiosis which is key to sexual reproduction producing gametes in the process e.g. sperm and eggs.

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

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 Kennedys 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 Kennedys disease

RanGAPAntibody - 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

RanGEF (RCC1) Antibody- Rabbit Anti-RanGEF
Ran GTPase plays important roles in nucleocytoplasmic transport in interphase and in both spindle formation and nuclear envelope (NE) assembly during mitosis The latter functions rely on the presence of high local concentrations of GTP bound Ran near mitotic chromatin RanGTP localization has been proposed to result from the association of Rans GDP/GTP exchange factor RCC1 with chromatin but Ran is shown here to bind directly to chromatin in two modes either dependent or independent of RCC1 and where bound to increase the affinity of chromatin for NE membranes

SMN (Gemin1) Antibody- Mouse Anti-SMN
This gene is part of a 500 kb inverted duplication on chromosome 5q13 This duplicated region contains at least four genes and repetitive elements which make it prone to rearrangements and deletions The repetitiveness and complexity of the sequence have also caused difficulty in determining the organization of this genomic region The telomeric and centromeric copies of this gene are nearly identical and encode the same protein However mutations in this gene the telomeric copy are associated with spinal muscular atrophy mutations in the centromeric copy do not lead to disease The centromeric copy may be a modifier of disease caused by mutation in the telomeric copy The critical sequence difference between the two genes is a single nucleotide in exon 7 which is thought to be an exon splice enhancer It is thought that gene conversion events may involve the two genes leading to varying copy numbers of each gene The protein encoded by this gene localizes to both the cytoplasm and the nucleus Within the nucleus the protein localizes to subnuclear bodies called gems which are found near coiled bodies containing high concentrations of small ribonucleoproteins (snRNPs) This protein forms heteromeric complexes with proteins such as SIP1 and GEMIN 4 and also interacts with several proteins known to be involved in the biogenesis of snRNPs such as hnRNP U protein and the small nucleolar RNA binding protein Two transcript variants are produced by this gene
