'''Protein kinase C, theta''', also known as '''PRKCQ''', is a human [[gene]].

[[Protein kinase C]] (PKC) is a family of serine- and threonine-specific [[protein kinase]]s that can be activated by 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 ester]]s, 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 transcription factor|AP-1]], and may link the [[T cell receptor]] (TCR) signaling complex to the activation of the [[transcription factor]]s.<ref>{{cite web | title = Entrez Gene: PRKCQ protein kinase C, theta| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=5588| accessdate = }}</ref>

Protein kinase C theta (PKC-θ) is an enzyme that in humans is encoded by the PRKCQ gene.[1]

Function

Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by 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.[2]

Interactions

PRKCQ has been shown to interact with:

PRKCQ has been shown to phosphorylate CARD11 as part of the NF-κB signaling pathway.[7]

Inhibitors

  • (R)-2-((S)-4-(3-Chloro-5-fluoro-6-(1H-pyrazolo[3,4-b]pyridin- 3-yl)pyridin-2-yl)piperazin-2-yl)-3-methylbutan-2-ol[8]
