Scientific Data Images for Human/Mouse/Rat UBASH3B/STS1 Antibody
Detection of Human and Rat UBASH3B/STS1 by Western Blot.
Western blot shows lysates of HCT-116 human colorectal carcinoma cell line, HEK293 human embryonic kidney cell line, MOLT-4 human acute lymphoblastic leukemia cell line, U-118-MG human glioblastoma/astrocytoma cell line, U2OS human osteosarcoma cell line, and Y3-Ag rat myeloid cell line. PVDF Membrane was probed with 2 µg/mL of Human/Rat UBASH3B/STS1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6696) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for UBASH3B/STS1 at approximately 72 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
UBASH3B/STS1 in HeLa Human Cell Line.
UBASH3B/STS1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Human/Mouse/Rat UBASH3B/STS1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6696) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red, upper panel; Catalog # NL010) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.Applications for Human/Mouse/Rat UBASH3B/STS1 Antibody

Background: UBASH3B/STS1
UBASH3B (Ubiquitin-associated domain SH3 domain-containing protein B; also STS1 and TULA2) is a cytosolic 72-74 kDa member of the TULA (T cell ubiquitin ligand) family of proteins. It is widely expressed and appears to perform multiple functions. As a histidine phosphatase, it dephosphorylates Syk and Syk-related molecules, thus dampening signaling pathways. Via ubiquitin and SH3 binding domains, it binds to monoubiquitinated RTKs and Cbl, thereby increasing RTK activity by blocking its polyubiquitination and subsequent lysosomal degradation. There is also the potential for phosphodiesterase activity directed towards tRNA activity. Human UBASH3B is 649 amino acids (aa) in length. It contains one UBA domain (aa 39-75), a proline-rich ligand binding SH3 region (aa 257-316), and a PGM/histidine phosphatase domain (aa 386-598). UBASH3B is suggested to dimerize. Over aa 47-253, human and mouse UBASH3B are identical in amino acid sequence.
