PRKCB Antibody Blocking Peptide

Calcium-activated， phospholipid- and diacylglycerol (DAG)-dependent serine/threonine-protein kinase involved in various cellular processes such as regulation of the B-cell receptor (BCR) signalosome， oxidative stress-induced apoptosis， androgen receptor-dependent transcription regulation， insulin signaling and endothelial cells proliferation. Plays a key role in B-cell activation by regulating BCR-induced NF-kappa-B activation. Mediates the activation of the canonical NF-kappa-B pathway (NFKB1) by direct phosphorylation of CARD11/CARMA1 at ’Ser-559’， ’Ser-644’ and ’Ser-652’. Phosphorylation induces CARD11/CARMA1 association with lipid rafts and recruitment of the BCL10-MALT1 complex as well as MAP3K7/TAK1， which then activates IKK complex， resulting in nuclear translocation and activation of NFKB1. Plays a direct role in the negative feedback regulation of the BCR signaling， by down-modulating BTK function via direct phosphorylation of BTK at ’Ser-180’， which results in the a
