STK16
Function
Membrane-associated protein kinase that phosphorylates on serine and threonine residues. In vitro substrates include DRG1, ENO1 and EIF4EBP1. Also autophosphorylates. May be involved in secretory vesicle trafficking or intracellular signaling. May have a role in regulating stromal-epithelial interactions that occur during ductal morphogenesis in the mammary gland. May be involved in TGF-beta signaling. Able to autophosphorylate on Tyr residue; it is however unclear whether it has tyrosine-protein kinase toward other proteins.
Post-translational modifications
Mainly autophosphorylated on serine/threonine residues. Also autophosphorylated on Tyr-198.
It is uncertain whether palmitoylation is on Cys-6 and/or Cys-8.
Sequence Similarities
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
Tissue Specificity
Ubiquitously expressed at very low levels.
Cellular localization
- Cytoplasm
- Perinuclear region
- Membrane
- Lipid-anchor
- Associates with Golgi and Golgi-derived vesicles.
