What residues are recognized in human insulin receptor β by your Phospho-IGF-I Receptor β (Tyr1135/1136)/Insulin Receptor β (Tyr1150/1151) (19H7) Rabbit mAb #3024?

Our Phospho-IGF-I Receptor β (Tyr1135/1136)/Insulin Receptor β (Tyr1150/1151) (19H7) Rabbit mAb #3024 recognizes Tyr1189/1190 in isoform 1 (Long) and Tyr1177/1178 in isoform 2 (Short) of human insulin receptor β (see Uniprot #P06213; https://www.uniprot.org/uniprotkb/P06213/entry#sequences). “Tyr1150/1151” reflects the position of the phosphosites in isoform 2 when the 27 amino acid signal peptide is removed from the N-terminus.
