PTPRN Antibody (PA5-76932) in ICC/IF
Immunofluorescence analysis of PTPRN was performed using 70% confluent log phase SH-SY5Y cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with PTPRN Polyclonal Antibody (Product # PA5-76932) at 1:100 in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32790), (...

靶标信息
IA-2 (insulinoma-associated protein 2, ICA512, PTPRN) is a member of the transmembrane protein tyrosine phosphatase (PTP) family located in secretory granules of neuroendocrine cells. The IA-2 protein is 979 amino acids in length and consists of a luminal domain, transmembrane domain, and cytoplasmic domain. Although a member of the PTP family, IA-2 lacks phosphatase activity with known substrates due to amino acid substitutions at critical sites in its PTP domain. Two paralog RPTPs, IA-2 and IA-2beta were identified as major autoantigens in type-1 diabetes mellitus. On granule exocytosis, the IA-2 cytoplasmic domain is cleaved and the resulting cytosolic fragment moves into the nucleus where it enhances the levels of phosphorylated STAT5 and STAT3, thereby inducing insulin gene transcription and granule biogenesis. IA-2 signaling enhances pancreatic beta-cell proliferation by regulating cyclins D through STATs.
