General annotation (Comments)
| Function | This is a calcium-independent, phospholipid-dependent, serine- and threonine-specific enzyme. PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins. PKC also serves as the receptor for phorbol esters, a class of tumor promoters. Subunit of a quaternary complex that plays a central role in epithelial cell polarization. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Enzyme regulation | Phosphatidylinositol 3,4,5-trisphosphate might be a physiological activator. Two specific sites, Thr-410 (activation loop of the kinase domain) and Thr-560 (turn motif), need to be phosphorylated for its full activation. |
| Subunit structure | Forms a ternary complex with SQSTM1 and KCNAB2. Forms another ternary complex with SQSTM1 and GABRR3. Forms a complex with SQSTM1 and MAP2K5 By similarity. Interacts with PARD6A, PARD6B, PARD6G and SQSTM1. Part of a complex with PARD3, PARD6A or PARD6B or PARD6G and CDC42 or RAC1. Interacts with ADAP1/CENTA1. Forms a ternary complex composed of SQSTM1 and PAWR. Interacts directly with SQSTM1 Probable. Interacts with IKBKB. Ref.7 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 Ref.14 |
| Subcellular location | Cytoplasm. Endosome. Note: In the retina, localizes in the terminals of the rod bipolar cells By similarity. Associates with endosomes. Ref.7 |
| Tissue specificity | Expressed in brain, and to a lesser extent in lung, kidney and testis. |
| Domain | The OPR domain mediates mutually exclusive interactions with SQSTM1 and PARD6B. Ref.14 The C1 domain does not bind the diacylglycerol (DAG). Ref.14 |
| Sequence similarities | Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily. Contains 1 AGC-kinase C-terminal domain. Contains 1 OPR domain. Contains 1 phorbol-ester/DAG-type zinc finger. Contains 1 protein kinase domain. |
