Alternative Products
Event=Alternative splicing, Alternative initiation; Named isoforms=3; Comment=Isoform 1 and isoform 3 result from alternative initiation of translation within the same 5' exon but produce the same functional protein following cleavage of their respective signal peptides (PubMed:18603590). Alternative initiation is probably a conserved mechanism in mammals to regulate the overall expression of that functional protein (PubMed:18603590, PubMed:33296397).; Name=1; IsoId=Q12913-1; Sequence=Displayed; Name=2; Synonyms=sPTPRJ; IsoId=Q12913-2; Sequence=VSP_043652, VSP_043653; Name=3; IsoId=Q12913-3; Sequence=VSP_060928
