RAPH1
Function
Mediator of localized membrane signals. Implicated in the regulation of lamellipodial dynamics. Negatively regulates cell adhesion.
Sequence Similarities
Belongs to the MRL family.
Tissue Specificity
Isoform RMO1-RAPH1 is ubiquitously expressed with highest levels in brain, heart, ovary and developing embryo. Isoform RMO1 is widely expressed with highest levels in liver. Low expression in B-cells.
Cellular localization

- Cytoplasmic side
- Cell projection
- Lamellipodium
- Cell projection
- Filopodium
- Cytoplasm
- Cytoskeleton
- Recruited to the membrane, via the PH domain, by the phosphoinositide, PI(3,4)P2. Colocalizes with ENAH/VASP at the tips of lamellipodia and filopodia. Also colocalizes with the pathogens, Vaccinia and Enteropathogenic E.coli (EPEC) at the interface between the pathogen and their actin.
