Checkpoint proteins play a key element in the regulation of the cell cycle. Checkpoints are made up of composites of protein kinases and adaptor proteins that are relevant for the integrity of the cell division process.
Examples are p53 that plays a role in halting the cell cycle in the G1 and has role in cell apoptosis. The ATM protein is involved in detecting double strand breaks in DNA and MAD can block entry to anaphase in cell division.

BUB1 Antibody - Mouse (monoclonal) Anti-BUB1 0.1ml
Bub1 is a kinase involved in spindle checkpoint function The kinase functions in part by phosphorylating a member of the miotic checkpoint complex and activating the spindle checkpoint Mutations in Bub1 have been associated with aneuploidy and several forms of cancer

CENP-E Antibody - Mouse Anti-CENP-E 0.1ml
CENPE is a 250-300 kDa human centromere-associated kinesin-like motor protein that accumulates in G2 phase In contrast to other centromere proteins CENPE is not detected at centromeres during interphase and first appears at the centromere region of chromosomes during prometaphase CENPE function is required for the transition from metaphase to anaphase CENPE is probably one of the motors responsible for mammalian chromosome movement and/or spindle elongation

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

MAD2 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.hMAD2 is the human homologue of yeast MAD2

MCPH1 (BRIT1) Antibody- Mouse Anti-MCPH1 (BRIT1)
This gene encodes a DNA damage response protein. The encoded protein may play a role in G2/M checkpoint arrest via maintenance of inhibitory phosphorylation of cyclin-dependent kinase 1. Mutations in this gene have been associated with primary autosomal recessive microcephaly 1 and premature chromosome condensation syndrome
MCPH1 looks like it might be a useful prognostic indicator in breast cancer associated with BRCA1 inactivation

Mus81 Antibody- Mouse Anti-Mus81
Reduction or loss of a protein called Mus81 can led to the development of lymphomas and other tumours in mice Mus81 is a protein long thought to be involved in repairing DNA that is damaged during normal metabolic processes

NEK2 Antibody- Sheep Anti-NEK2
NEK2 is closely related in its catalytic domain to the serine/threonineprotein kinase NIMA of Aspergillus nidulans which is required for entry into mitosis and may function in parallel to the universal mitotic inducer p34cdc2. Like NIMA, the Nek2 protein is almost undetectable during G1 but accumulates progressively throughout S, reaching maximal levels in late G2. These observations demonstrate that NEK2 resembles Aspergillus NIMA, both in its catalytic domain, and cell cycle-dependent expression. Recombinant NEK2 is active as a serine/threonine-specific protein kinase and may undergo autophosphorylation. Both human NEK2 and fungal NIMA phosphorylate a similar, but not identical, set of proteins and synthetic peptides. NEK2 is shown to be expressed most abundantly in adult testis and there is increasing evidence that NEK2 is abnormally expressed in a wide variety of human cancers

ORC3 (origin recognition complex 3) Antibody- Rat Anti-ORC3
The origin recognition complex (ORC) is a highly conserved six subunits protein complex essential for the initiation of the DNA replication in eukaryotic cells Studies in yeast demonstrated that ORC binds specifically to origins of replication and serves as a platform for the assembly of additional initiation factors such as Cdc6 and Mcm proteins ORC3 is a subunit of the ORC complex Studies of a similar gene in Drosophila suggested a possible role of this protein in neuronal proliferation and olfactory memory
