Summary: Predicted to enable peroxidase activity. Involved in several processes, including embryonic body morphogenesis; muscle attachment; and negative regulation of axon regeneration. Located in basement membrane. Is expressed in PVQL; PVQR; hypodermis; and vulval muscle. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease 1; anterior segment dysgenesis 7; kidney failure (multiple); liver disease (multiple); and lung disease (multiple). Orthologous to several human genes including PXDN (peroxidasin) and PXDNL (peroxidasin like). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

There is a negative relationship between pxn-1 and pxn-2 via pxn-1 regulating pxn-2. Therefore, pxn-1 may function in neuronal development and age-related neuronal maintenance through pxn-2.
Title: pxn-1 and pxn-2 May Interact Negatively during Neuronal Development and Aging in C. elegans.
Peroxidasins are crucial in development and play new role as extracellular inhibitors of axonal regeneration.
Title: The C. elegans peroxidasin PXN-2 is essential for embryonic morphogenesis and inhibits adult axon regeneration.
