Description de la cible

Receptor tyrosine-protein kinase erbB-4 (UniProt: Q15303; also known as EC:2.7.10.1, Proto-oncogene-like protein c-ErbB-4, Tyrosine kinase-type cell surface receptor HER4, p180erbB4) is encoded by the ERBB4 (also known as HER4) gene (Gene ID:  2066) in human. erbB4 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-25), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 26-651), a transmembrane domain (aa 652-675), and a cytoplasmic domain (aa 676-1308). Its higher expression is observed in brain, heart, kidney, skeletal muscle, spleen, testis, and breast tissue. Lower expression is observed in thymus, lung, pancreas, and salivary glands. erbB4 is a tyrosine-protein kinase that serves as a receptor for neuregulins and EGF family members. Its protein kinase domain is localized in amino acids 718-985. It is required for normal cardiac muscle differentiation during embryonic development, and for postnatal cardiomyocyte proliferation. It is also required for normal development of the embryonic central nervous system, especially for normal neural crest cell migration and normal axon guidance. Ligand binding to erbB4 triggers receptor dimerization and autophosphorylation at specific tyrosine residues that then serve as binding sites for scaffold proteins and effectors. It is constitutively phosphorylated at a basal level and ligand binding LEADS^™ to increased phosphorylation. Phosphorylation at Tyr-1035 is important for its interaction with STAT1 and phosphorylation at Tyr-1056 is required for its interaction with phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1). Its phosphorylation at Tyr-1242 is important for interaction with SHC adaptor protein 1 (SHC1). erbB4 can be proteolytically processed to generate an intracellular domain (4ICD) that can translocate to nucleus to promote import and activation of STAT5A. 4ICD also translocates to mitochondria where it promotes apoptosis. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
