Gene Information

rabbit ... Rad21(5885)

General description

RAD21 (RAD21 homolog, S. pombe) is a novel nuclear protein located on chromosome 8q24.

Immunogen

The epitope recognized by PLA0022 maps to a region between residue 575 and the C-terminus (residue 631) human Rad21 homolog using the numbering given in entry NP_006256.1 (GeneID 5885).

Biochem/physiol Actions

RAD21 (RAD21 homolog, S. pombe) plays a crucial role in normal cell division. It acts as a main component of the cohesin complex for the proper chromosomal arrangement during cell division. The protein possesses two mitotic cleavage sites for the attachment of separase. It has been shown experimentally that at the beginning of anaphase stage, a caspase-like Esp1/separase attaches to the cleavage site of RAD21 and initiate sister chromatid separation, which is an essential step for the completion of cytokinesis. During double strand DNA damage repair, it helps the two DNA strands to adhere with each other. Mutation in RAD21 causes a congenital phenotype, cohesinopathy in humans characterized with growth retardation and minor skeletal anomalies.

Physical form

Tris-citrate/phosphate buffer, pH 7 to 8 containing 0.09% Sodium Azide

Other Notes

Rad21, also called SCC1 (sister chromatid cohesion protein 1), is part of the mitotic cohesin complex that consist of SMC1, SMC3, SCC3 and SCC1. The cohesin complex is important to sister chromatid separation and segregation during mitosis and meiosis and also plays a role in double-strand break repair by homologous recombination. Rad21 has been demonstrated to be cleaved by caspase proteins to trigger sister chromatid separation and during apoptotic signaling.

The evolutionarily conserved cohesin complex was originally described for its role in regulating sister-chromatid cohesion during mitosis and meiosis. Cohesin and its regulatory proteins have been implicated in several human developmental disorders, including Cornelia de Lange (CdLS) and Roberts syndromes.
