Enables protein kinase C activity. Involved in several processes, including positive regulation of NF-kappaB transcription factor activity; positive regulation of cytokine production; and regulation of cell-cell adhesion. Acts upstream of or within several processes, including positive regulation of 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, Apr 2022]
