Summary: Enables ephrin receptor binding activity and protein domain specific binding activity. Predicted to be involved in endoplasmic reticulum membrane organization and endoplasmic reticulum-plasma membrane tethering. Predicted to be located in cytoskeleton and membrane. Predicted to be active in endoplasmic reticulum membrane and plasma membrane. Is expressed in several structures, including body wall musculature; gonad; intestine; muscle cell; and nervous system. Used to study amyotrophic lateral sclerosis. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis; amyotrophic lateral sclerosis type 8; autosomal dominant adult-onset proximal spinal muscular atrophy; and spinal muscular atrophy. Orthologous to human VAPA (VAMP associated protein A) and VAPB (VAMP associated protein B and C). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

The type II integral ER membrane protein VAP-B homolog in C. elegans is cleaved to release the N-terminal MSP domain to signal non-cell-autonomously.
Title: The type II integral ER membrane protein VAP-B homolog in C. elegans is cleaved to release the N-terminal MSP domain to signal non-cell-autonomously.
Maternal or zygotic vpr-1 expression is sufficient to induce gonadogenesis and fertility. Genetic mosaic and cell type-specific expression studies indicate that vpr-1 activity is important in the nervous system, germ line and intestine.
Title: The C. elegans VAPB homolog VPR-1 is a permissive signal for gonad development.
The major sperm protein domain (MSPd) has an extracellular signaling function implicated in amyotrophic lateral sclerosis. Secreted MSPds derived from the VAPB homolog VPR-1 promote mitochondrial localization to actin-rich I-bands in body wall muscle.
Title: The secreted MSP domain of C. elegans VAPB homolog VPR-1 patterns the adult striated muscle mitochondrial reticulum via SMN-1.
