PF14843Growth factor receptor domain IV (GF_recep_IV)Growth factor receptor domain IVThis is the fourth extracellular domain of receptor tyrosine protein kinases. Interaction between this domain and the furin-like domain (Pfam:PF00757) regulates the binding of ligands to the receptor L domains (Pfam:PF01030) [1]. Domain

Pfam:PF00053 is very similar, but has 8 instead of 6 conserved cysteines. Includes some cytokine receptors. The EGF domain misses the N-terminus regions of the Ca2+ binding EGF domains (this is the main reason of discrepancy between swiss-prot domain start/end and Pfam). The family is hard to model due to many similar but different sub-types of EGF domains. Pfam certainly misses a number of EGF domains.
