Protein

Anthrax toxin receptor 1

Gene

ANTXR1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Plays a role in cell attachment and migration. Interacts with extracellular matrix proteins and with the actin cytoskeleton. Mediates adhesion of cells to type 1 collagen and gelatin, reorganization of the actin cytoskeleton and promotes cell spreading. Plays a role in the angiogenic response of cultured umbilical vein endothelial cells.2 Publications

Involvement in diseasei

Hemangioma, capillary infantile (HCI)1 Publication
Disease susceptibility is associated with variations affecting the gene represented in this entry.
Disease descriptionA condition characterized by dull red, firm, dome-shaped hemangiomas, sharply demarcated from surrounding skin, usually presenting at birth or occurring within the first two or three months of life. They result from highly proliferative, localized growth of capillary endothelium and generally undergo regression and involution without scarring.
See also OMIM:602089
GAPO syndrome (GAPO)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA disease characterized by growth retardation, alopecia, failure of tooth eruption, and progressive optic atrophy in some patients.
