Official Full Name: protein kinase D3
Also known as: EPK2; PKD3; PRKCN; PKC-NU; nPKC-NU
This gene belongs to the multigene protein kinase D family of serine/threonine kinases that bind diacylglycerol and phenolic esters. Members of this family are characterized by an N-terminal regulatory domain consisting of tandem repeats of cysteine-rich zinc finger motifs and a pleckstrin domain. The C-terminal region contains the catalytic domain and is distantly related to calcium-regulated kinases. The catalytic activity of the enzyme facilitates its nuclear localization. The protein has been implicated in a variety of functions, including negative regulation of human airway epithelial barrier formation, growth regulation of breast and prostate cancer cells, and vesicle trafficking.
