Oxidative stress responsive 1 (OXSR1) is a 58kDa protein having 527 amino acids. It belongs to the Ste20p family of proteins which are serine/threonine-protein kinases. OXSR1 is expressed in mammalian tissues and cell lines.
Synonyms: Anti-Oxidative stress-responsive 1 protein antibody produced in rabbit; Anti-Serine/threonine-protein kinase OSR1 antibody produced in rabbit
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: Oxidative stress responsive 1 (OXSR1) phosphorylates the threonine-84 residue in the amino-terminal regulatory domain of the p21-activated protein kinase (PAK1), thereby modulating the G protein sensitivity of PAK1. It also regulates and modulates the activities of PAK2 and PAK3. The carboxyl-terminus of OXSR1 binds to gelsolin, an actin-binding protein. It associates with growing ends of actin filaments and nucleates actin assembly. Thus, OXSR1 regulates the actin cytoskeleton. It also interacts with and phosphorylates three RELT (Receptor expressed in lymphoid tissues) family members, RELT, RELL2 (RELT-like protein 2) and RELL1 which are involved in tumor necrosis factor (TNF) receptor mediated pathway.
