G antigen 1; GAGE-1; antigen MZ2-F; cancer/testis antigen 4.1; CT4.1 (GAGE1)

Function

• antigen
  • recognized on melanoma by autologous cytolytic T-cells (see Genetics:)
• completely silent in normal adult tissues, except testis

Structure

belongs to the GAGE family

Expression

• exressed specifically in testis

Pathology

• expressed in several tumor tissues including melanoma

Genetics

• gene belongs to a family of genes organized in clustered repeats
  • the genes have a high degree of predicted sequence identity, but differ by scattered single nucleotide substitution
  • their sequences contain either the antigenic peptide YYWPRPRRY or YRPRPRRY which is recognized by cytotoxic T-cells

More general terms

• GAGE protein (G antigen family)
• phosphoprotein
• testis-specific protein
