Summaries for GGTLC2 Gene

Entrez Gene Summary for GGTLC2 Gene

  • This gene encodes a protein related to enzymes that cleaves gamma-glutamyl peptide bonds in glutathione and other peptides. Unlike similar proteins, the encoded protein contains only the light chain portion and may not have catalytic activity. Alternative splicing results in multiple transcript variants. There are several related family members and related pseudogene for this gene situated in the same region of chromosome 22. [provided by RefSeq, Sep 2013]
