Anti-PSKH1 antibodies are used in the immunodetection of the protein protein serine kinase H1. In humans, the canonical protein has a reported length of 424 amino acid residues and a mass of 48 kDa. Its subcellular localization is in the cell membrane, nucleus, ER, golgi, and cytoplasm. It is reported to be expressed in all tissues and cell lines tested with the highest level of abundance in testis. A member of a the CAMK Ser/Thr protein kinase protein family, PSKH1 is believed to 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. Post-translational modifications have been described, including palmitoylation, myristoylation and phosphorylation. Synonyms for this target antigen include serine/threonine-protein kinase H1.
