CTCL is an alias for the gene, TSPY-like 2, in humans. Other names include: Testis-specific Y-encoded-like protein 2; Cell division autoantigen 1; Cutaneous T-cell lymphoma-associated antigen se20-4-associated antigen se20-4; Differentially-expressed nucleolar TGF-beta1 target protein; Nuclear protein of 79 kDa; NP79; TSPY-like protein 2; CINAP; DENTT; HRIHFB2216; SE204; TSPX. The encoded protein has an amino acid length of 693 and a mass of 79.4 kDa. Other isoforms may exist. CTCL is a member of the Nucleosome assembly protein (NAP) family. This gene shares homology with other species, including: Mouse, Frog.
