CBL (E3 Ubiquitin-protein Ligase CBL, Casitas B-lineage Lymphoma Proto-oncogene, Proto-oncogene c-Cbl, RING Finger Protein 55, Signal Transduction Protein CBL, CBL2, RNF55)

The mammalian cbl family of ubiquitin ligases consists of three homologs known as cbl (also known as c-Cbl), Cbl-B, and Cbl-3 which share highly conserved a tyrosine-kinase-binding domain, linker and RING finger domain in their amino-terminal halves. Similar to other E3 ubiquitin ligases, Cbl catalyzes the transfer of ubiquitin from an E2 or Ubc (ubiquitin-conjugating) enzyme to the e-amino group of a lysine residue of the substrate protein. Cbl acts to negatively regulate many types of cell-surface receptors, including the Syk protein tyrosine kinase family. Cbl is thought to be involved in T- and B-cell signaling, in addition to thymus development. Of the three known homologs in the cbl family, cbl antibody reacts specifically with cbl. Multiple isoforms of cbl have been reported.\n\nApplications:\nSuitable for use in Immunofluorescence, ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 0.5-2ug/ml\nImmunofluorescence: 20ug/ml\nOptimal dilutions to be determined by the researcher.\n\nPositive Control:\nDaudi Cell Lysate or Human Lymph node Tissue Lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
