Trp63, or Tumor protein p63, is a human gene encoded by TP63. It may also be known as: Tumor protein 63; Chronic ulcerative stomatitis protein; CUSP; Keratinocyte transcription factor KET; Transformation-related protein 63; Tumor protein p73-like; p73L; B(p51A); B(p51B); EEC3; KET; LMS; OFC8; RHS; SHFM4; TP53CP; TP53L; TP73L; p53CP; p73H. The encoded protein has an amino acid length of 680 and a mass of 76.8 kDa. Trp63 is a member of the P53 family. Homologs of this gene exist in other organisms, including: Fly, Rat, Frog.
