Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Species predicted to react based on 100% sequence homology: Chicken, D. melanogaster, Xenopus, Zebrafish.
Specificity / Sensitivity
HR6A/HR6B Antibody detects endogenous levels of total HR6A and HR6B proteins.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids at the amino-terminus of human HR6A. Antibodies are purified by protein A and peptide affinity chromatography.

The ubiquitin-conjugating (UBC) enzymes HR6A and HR6B are the mammalian orthologues of the Saccharomyces cerevisiae Rad6 gene products (1). In S. cerevisiae, Rad6 facilitates cell cycle progression and ubiquitinates histone H2B (2,3). In vivo phosphorylation of HR6A Ser120 by cyclin-dependent kinases is thought to be important for the coordination and timing of ubiquitination events involved in cell cycle progression (4). In response to DNA damage, HR6A is known to interact physically with p53 and p14ARF, but knockout mice lacking HR6A or HR6B exhibit normal DNA damage responses (5,6). HR6B knockout males exhibit defective spermatogenesis, while HR6A knockout females fail to produce viable offspring (6).
