Description
ErbB4 (Her4) Monoclonal Antibody (HFR1), eBioscience?. ErbB 4 (Her-4, c-erbB-4, v-erbB-4) is a member of the class I receptor kinase family. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. ErbB 4 is activated by neuregulins and NTAK (neural and thymus derived activator for ErbB kinases). ErbB 4 is a receptor for heregulin and is capable of mediating HGL-stimulated tyrosine phosphorylation of itself. Like other protein kinases, ErbB 4 mediate most of the signal transduction in eukaryotic cells, regulating cellular m
