Target

  • FunctionBinds and is activated by neuregulins and NTAK.
  • Tissue specificityEpithelial tissues and brain.
  • Involvement in diseaseDefects in ERBB3 are the cause of lethal congenital contracture syndrome type 2 (LCCS2) [MIM:607598]; also called Israeli Bedouin multiple contracture syndrome type A. LCCS2 is an autosomal recessive neurogenic form of a neonatally lethal arthrogryposis that is associated with atrophy of the anterior horn of the spinal cord. The LCCS2 syndrome is characterized by multiple joint contractures, anterior horn atrophy in the spinal cord, and a unique feature of a markedly distended urinary bladder. The phenotype suggests a spinal cord neuropathic etiology.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.
    Contains 1 protein kinase domain.
  • Developmental stageOverexpressed in a subset of human mammary tumors.
  • DomainThe cytoplasmic part of the receptor may interact with the SH2 or SH3 domains of many signal-transducing proteins.
  • Post-translational
    modifications
    Ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase.
  • Cellular localizationSecreted and Cell membrane.

Anti-ErbB 3 antibody images

  • ICC/IF image of ab79537 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab79537, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your reply.

Thank you for bringing this to my attention. It does indeed appear that this antibody binds to the 19 amino acid N-terminal signaling sequence. I was only able to find limited reference as to how this is cleaved. Read More
