Specificity / Sensitivity
CABIN1 (D2B9F) Rabbit mAb recognizes endogenous levels of total CABIN1 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human CABIN1 protein.
Background
Calcineurin binding protein CABIN1 was originally identified as an inhibitor of the calcium-dependent serine/threonine phosphatase, calcineurin. CABIN1 inhibits calcineurin signaling in T cells, regulating T cell receptor (TCR) signaling, transcription, and apoptosis (1-4). CABIN1 represses myocyte enhancer factor 2 (MEF2)-mediated transcription by recruiting chromatin remodeling enzymes (5), and also negatively regulates the activity of the tumor suppressor p53 (6). In response to genotoxic stress, CABIN1 is degraded and releases its inhibition of p53, allowing p53 to elicit cellular stress responses (7). CABIN1 is also involved in regulation of chromatin structure as part of the highly conserved HIRA/UBN1/CABIN1/ASF1A (HUCA) histone chaperone complex (8,9).
