The abbreviation trk (often pronounced 'track') stands for tropomyosin receptor kinase or tyrosine receptor kinase (and not "tyrosine kinase receptor" nor "tropomyosin-related kinase", as has been commonly mistaken). The family of Trk receptors is named for the oncogene trk, whose identification led to the discovery of its first member, TrkA. Trk, initially identified in a colon carcinoma, is frequently (25%) activate… WebAcquired Resistance to TRK Inhibitors. Resistance to TRK inhibition by larotrectinib and entrectinib can occur through the development of NTRK gene mutations, which involves amino acid substitutions in the solvent-front, gatekeeper residues of the NTRK genes ( NTRK1 p. G667C, NTRK3 p. G696A) and xDFG motif substitutions [1, 2].
