PRKCQ, also named as PRKCT and nPKC-theta, belongs to the protein kinase superfamily, AGC Ser/Thr protein kinase family and PKC subfamily. PRKCQ catalyzes the reaction: ATP + a protein = ADP + a phosphoprotein. PRKCQ is a calcium-independent, phospholipid-dependent, serine- and threonine-specific enzyme. It is essential for T-cell receptor (TCR)-mediated T-cell activation, but it is dispensable during TCR-dependent thymocyte development. PRKCQ links the TCR signaling complex to the activation of NF-kappa-B in mature T lymphocytes. It is required for interleukin-2 (IL2) production. PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins. PKC also serves as the receptor for phorbol esters, a class of tumor promoters. This antibody is specific to PRKCQ.
