General annotation (Comments)

Function

Cleaves the gamma-glutamyl peptide bond of glutathione conjugates, but maybe not glutathione itself. Converts leukotriene C4 (LTC4) to leukotriene D4 (LTD4).

Catalytic activity

(5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl amino acid.

Glutathione + H2O = L-cysteinylglycine + L-glutamate.

Pathway

Sulfur metabolism; glutathione metabolism.

Lipid metabolism; leukotriene D4 biosynthesis.

Subunit structure

Heterodimer composed of the light and heavy chains. The active site is located in the light chain By similarity.

Subcellular location

Membrane; Single-pass type II membrane protein By similarity.

Tissue specificity

Very low level of expression. Detected in spleen lymphocytes, medullary and paracortical thymic lymphocytes, lung interstitial cells, bronchial epithelium, proximal tubules in kidney, crypt cells in small intestine, neurons in brain stem and cerebral cortex and in Purkinje cells.

Sequence similarities

Belongs to the gamma-glutamyltransferase family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9Z2A9-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q9Z2A9-2)

The sequence of this isoform differs from the canonical sequence as follows:
     447-456: VPGERPPSSM → DYHEQAVAWL
     457-573: Missing.
Note: Very low expression.
