PTPRZ1 (E7C8Z) Rabbit mAb (BSA and Azide Free) #19558

PTPRZ1, also known as protein tyrosine phosphatase receptor zeta, is a highly glycosylated membrane protein that is expressed abundantly in normal brain, in a spatially restricted pattern. The functions of PTPRZ1 in neural tissue are thought to be diverse, including development, neural development, neural myelination, and memory formation (1). PTPRZ1 can be found in 2 forms, a membrane-associated glycosylated form and a non-glycosylated, secreted form. In patients with glioma, the soluble form is found to be unregulated in cerebrospinal fluid (2). It is for this and other reports, that PTPRZ1 is a target of pharmaceutical interest. PTPRZ1 has also been reported to be upregulated. Interestingly, increased expression of both membrane bound and soluble PTPRZ1 has also been found in various cancer types, including breast, lung, cervical, hepatocellular carcinoma, and renal tumors (3). In breast cancer, the distribution between localizations of membrane and soluble forms has been reported to change with cancer development, progression, and metastasis.
