Recombinant Human Serine/threonine-protein kinase H1 (PSKH1)

Uniprot Id

P11801

Target Species

Human

Target Name

PSKH1

Target Full Name

Serine/threonine-protein kinase H1

Target Function

May be a SFC-associated serine kinase (splicing factor compartment-associated serine kinase) with a role in intranuclear SR protein (non-snRNP splicing factors containing a serine/arginine-rich domain) trafficking and pre-mRNA processing.

Target Subcellular Location

Golgi apparatus. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Nucleus speckle. Endoplasmic reticulum membrane; Lipid-anchor. Cell membrane; Lipid-anchor. Cytoplasm. Note=Localized in the brefeldin A-sensitive Golgi compartment, at centrosomes, in the nucleus with a somewhat speckle-like presence, membrane-associated to the endoplasmic reticulum (ER) and the plasma membrane (PM), and more diffusely in the cytoplasm. Found to concentrate in splicing factor compartments (SFCs) within the nucleus of interphase cells. The acylation-negative form may be only cytoplasmic and nuclear. Acylation seems to allow the sequestering to the intracellular membranes. Myristoylation may mediate targeting to the intracellular non-Golgi membranes and palmitoylation may mediate the targeting to the Golgi membranes. Dual acylation is required to stabilize the interaction with Golgi membranes.

Target Protein Families

Protein kinase superfamily, CAMK Ser/Thr protein kinase family

Target Tissue Specificity

Expressed in all tissues and cell lines tested with the highest level of abundance in testis.
