>cd05111 PTK_HER3 Pseudokinase Domain of the Protein Tyrosine Kinase, HER3. Protein Tyrosine Kinase (PTK) family; HER3 (ErbB3); pseudokinase domain. The PTKc (catalytic domain) family to which this subfamily belongs, is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. HER3 is a member of the EGFR (HER, ErbB) subfamily of proteins, which are receptor tyr kinases (RTKs) containing an extracellular EGF-related ligand-binding region, a transmembrane helix, and a cytoplasmic region with a tyr kinase domain and a regulatory C-terminal tail. Unlike other tyr kinases, phosphorylation of the activation loop of EGFR proteins is not critical to their activation. Instead, they are activated by ligand-induced dimerization, leading to the phosphorylation of tyr r
