Summary: Enables diacylglycerol-dependent serine/threonine kinase activity. Involved in several processes, including positive regulation of T-helper 17 type immune response; regulation of cell-cell adhesion; and regulation of gene expression. Acts upstream of or within several processes, including positive regulation of CD4-positive, alpha-beta T cell proliferation; positive regulation of interleukin-2 production; and protein phosphorylation. Located in cytoplasm and immunological synapse. Is expressed in several structures, including adipose tissue; genitourinary system; gut; limb; and nervous system. Used to study retinal detachment. Orthologous to human PRKCQ (protein kinase C theta). [provided by Alliance of Genome Resources, Nov 2024]

These findings demonstrate that PKCtheta; plays an important role in a positive feedback regulatory loop that modulates TCR-proximal signaling and, moreover, provide a mechanistic explanation for earlier reports that documented an important role for PKCtheta; in T cell Ca(2+) signaling. This PKCtheta;-Zap70 interaction could potentially serve as a promising and highly selective immunosuppressive drug target in autoimmu...
Title: Phosphotyrosine-dependent interaction between the kinases PKCθ and Zap70 promotes proximal TCR signaling.
The authors established that OX40L/OX40 interaction was required and sufficient to induce regulatory T-cell proliferation in vivo independent of PKC- status. Although PKC- is dispensable for T-cell receptor-independent regulatory T-cell proliferation per se, it is essential for optimum IL-2 production by effector T-cells.

PKC-theta; is a regulator of lipid-induced insulin resistance in skeletal muscle.
Title: Mice lacking PKC-θ in skeletal muscle have reduced intramyocellular lipid accumulation and increased insulin responsiveness in skeletal muscle.
Comparison with expanded cord blood-derived CD4(+)CD25(hi) tTreg and expanded Teffs from the same donors indicate that iTreg are intermediate between expanded CD4(+)CD25(hi) tTregs and Teffs, whereas modulation of suppressive activities by PKC-theta; and Dlgh1 signaling pathways are shared.
Title: Human in vitro-induced regulatory T cells display Dlgh1dependent and PKC-θ restrained suppressive activity.
PKCtheta; selectively inactivates the negative regulator of F-actin generation, Coronin 1A, at the center of the T cell interface with the antigen presenting cell (APC). This allows for effective generation of the large actin-based lamellum required for recruitment of the Notch-processing membrane metalloproteinase ADAM10.
Title: PKCθ links proximal T cell and Notch signaling through localized regulation of the actin cytoskeleton.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
