CC   -!- TISSUE SPECIFICITY: Expressed in testis and melanoma cell lines.
CC       {ECO:0000269|PubMed:10790436}.
CC   -!- CAUTION: Could be the product of a pseudogene. This peptide sequence
CC       originates from a processed pseudogene derived from a retro-transcript
CC       of the mRNA coding for VENTX. The protein sequence is translated from a
CC       region that corresponds to the 3'-UTR of the original gene.
CC       {ECO:0000305}.
