Protein Information
Name CD99
Synonyms MIC2, MIC2X, MIC2Y
Function Involved in T-cell adhesion processes and in spontaneous rosette formation with erythrocytes. Plays a role in a late step of leukocyte extravasation helping leukocytes to overcome the endothelial basement membrane. Acts at the same site as, but independently of, PECAM1. Involved in T-cell adhesion processes (By similarity).
Cellular Location Membrane; Single-pass type I membrane protein

CD99, or protein MIC2, is a T-cell surface glycoprotein involved in the T-cell adhesion process and spontaneous rosette formation with erythrocytes. (1). The cell surface antigen defined by the monoclonal antibody CD99 is expressed by both the human X and Y chromosomes; the gene loci on the X and Y chromosomes are referred to as MIC2X and MIC2Y, respectively (2). It was demonstrated that engagement of distinct epitopes on CD99 rapidly induces T cell death by a novel caspase-independent pathway. Thus, it is suggested that CD99 is linked to a novel death pathway that may have biologic relevance in control of early T cells (3).
