Table 2 C-terminal isoforms of mouse MOP.

From: HA-MOP knockin mice express the canonical µ-opioid receptor but lack detectable splice variants

  1. Alignment of MOP splice variant sequences. UniProtKB/Swiss-Prot identifiers are given in Supplementary Table S1. Isoforms predicted not to contain the HA-tag have been omitted. Only portions of the sequence containing MS-identified peptides or putative splice variant alternative peptides are shown. *, fully conserved part of the sequence. In green, peptides are identified by nanoLC–MS/MS. In blue, other putative splice variant peptides that could have been detected by MS. Highlighted in gray, trypsin cleavage sites. Highlighted in red, phosphorylated residues identified by nanoLC–MS/MS.
