Description
Product Characteristics: Proteins in this family participate in pathways regulated by reversible phosphorylation at serine and threonine residues, potentially playing a role in the regulation of cell growth and differentiation. PP5 or PPT is predominantly a nuclear protein and interacts with CDC16 and CDC27. It is found in association with several proteins that influence intracellular signlaing-cascades intitiated by hormones (glucocorticoids) or cellular stress (hypoxia, oxidative stress and DNA Damage). It phosphorylates serine residues of skeletal muscle phosphorylase and histone H1. It may also be involved in mitosis and RNA biogenesis regulation (1,2).
Target Information: This gene encodes a member of the Kunitz-type serine proteinase inhibitor family. The protein can inhibit a variety of serine proteases including factor VIIa/tissue factor, factor Xa, plasmin, trypsin, chymotryspin and plasma kallikrein. This gene has been identified as a tumor suppressor gene in several types of cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]
