    Summary
    Enables thioredoxin-dependent peroxiredoxin activity. Involved in intestinal stem cell homeostasis; response to endoplasmic reticulum stress; and response to oxidative stress. Located in Golgi apparatus. Is expressed in several structures, including adult head; adult heart; amnioserosa; embryonic/larval fat body; and germline cell. Human ortholog(s) of this gene implicated in colorectal adenocarcinoma; colorectal cancer; and spondylometaphyseal dysplasia Sedaghatian type. Orthologous to human GPX4 (glutathione peroxidase 4).
