CC -!- FUNCTION: Involved in T-cell adhesion processes and in spontaneous
CC rosette formation with erythrocytes. Plays a role in a late step of
CC leukocyte extravasation helping leukocytes to overcome the endothelial
CC basement membrane. Acts at the same site as, but independently of,
CC PECAM1. Involved in T-cell adhesion processes (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass type I
CC membrane protein {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=I;
CC IsoId=P14209-1; Sequence=Displayed;
CC Name=II;
CC IsoId=P14209-2; Sequence=VSP_004324;
CC Name=3;
CC IsoId=P14209-3; Sequence=VSP_046315;
CC -!- PTM: Extensively O-glycosylated.
CC -!- MISCELLANEOUS: The gene coding for this protein is located in the
CC pseudoautosomal region 1 (PAR1) of X and Y chromosomes.
CC -!- SIMILARITY: Belongs to the CD99 family. {ECO:0000305}.
