Summary: Predicted to be an extracellular matrix structural constituent conferring tensile strength. Involved in several processes, including positive regulation of axon regeneration; positive regulation of protein secretion; and response to serotonin. Located in basement membrane. Is expressed in several structures, including GLR; head; head mesodermal cell; muscle cell; and reproductive system. Human ortholog(s) of this gene implicated in several diseases, including Alport syndrome (multiple); X-linked deafness 6; artery disease (multiple); benign familial hematuria; and brain small vessel disease 1. Orthologous to several human genes including COL4A1 (collagen type IV alpha 1 chain). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

A dominant mutation in the EMB-9/type IV collagen alpha1 subunit can compensate for loss of FBL-1 activity in gonadogenesis.
Title: Tissue architecture in the Caenorhabditis elegans gonad depends on interactions among fibulin-1, type IV collagen and the ADAMTS extracellular protease.
