Anti-RAD21 Antibody detects endogenous levels of total RAD21 protein.
RAD21 (RAD21 homolog, S. pombe) is a novel nuclear protein located on chromosome 8q24.
Immunogen
The antiserum was produced against synthesized peptide derived from human RAD21.
Immunogen Range: 521-570
Application
Anti-RAD21, C-Terminal antibody produced in rabbit is suitable for indirect ELISA and western blot applications.
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.

Caspases are a conserved family of proteases that play a critical role in the execution of apoptosis by cleaving key cellular proteins at Asp residues and modifying their function. Using an expression cloning strategy we recently developed, we isolated human
To detect genes that are overexpressed in prostate cancer, a subtracted cDNA library was first constructed from the PC-3 cell line and subsequently screened by using cDNA microarray hybridization. Sixty-eight genes were found to be overexpressed (ratio>3) in PC-3. Half

Rad21 is one of the major cohesin subunits that holds sister chromatids together until anaphase, when proteolytic cleavage by separase, a caspase-like enzyme, allows chromosomal separation. We show that cleavage of human Rad21 (hRad21) also occurs during apoptosis induced by

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.
