PKC Theta (Ps676) (PRKCQ) Antibody – Rabbit Polyclonal

Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role. The protein encoded by this gene is one of the PKC family members. It is a calcium-independent and phospholipid-dependent protein kinase. This kinase is important for T-cell activation. It is required for the activation of the transcription factors NF-kappaB and AP-1, and may link the T cell receptor (TCR) signaling complex to the activation of the transcription factors.

PKCT: an AGC kinase of the PKC family. A novel PKC: Ca2+ independent but still regulated by PS, DAG and phorbol esters. Contains 2 zinc-dependent phorbol-ester and DAG binding domains. Expressed in skeletal muscle and hematopoietic cells. May play a role in T cell receptor signaling and insulin resistance. Required for TCR-induced NF-kappaB activation in mature T lymphocytes.
