Systematic name: ATP:[protein]-L-tyrosine O-phosphotransferase (receptor-type)

Comments: The receptor protein-tyrosine kinases, which can be defined as having a transmembrane domain, are a large and diverse multigene family found only in Metazoans [1]. In the human genome, 58 receptor-type protein-tyrosine kinases have been identified and these are distributed into 20 subfamilies.
