Anti-CBLL2 antibodies are used in the immunodetection of the protein Cbl proto-oncogene like 2. In humans, the canonical protein has a reported length of 425 amino acid residues and a mass of 48.8 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the testis and sperm, including spermatocytes, round and elongated spermatids, and Leydig cells. CBLL2 is known to be involved with protein ubiquitination. Synonyms for this target antigen include E3 ubiquitin ligase, E3 ubiquitin-protein ligase ZNF645, RING-type E3 ubiquitin transferase ZNF645, c-Cbl-like protein 2, and E3 ubiquitin-protein ligase CBLL2. CBLL2 gene orthologs have been reported in the mouse and chimpanzee species. These CBLL2 antibodies are widely used in Western Blot experiments, among other applications.
