Protein

Anthrax toxin receptor 1

Gene

ANTXR1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-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.

Feature keyPosition(s)DescriptionActionsGraphical viewLength
Natural variantiVAR_063146326A → T in HCI susceptibility; expression of FLT1 in hemangioma endothelial cells is markedly reduced compared to controls; low FLT1 expression in hemangioma cells is caused by reduced activity of a pathway involving ITGB1, ANTXR1, KDR and NFATC2IP; the mutation disrupts interaction of these molecules in a dominant-negative manner. 1 PublicationCorresponds to variant dbSNP:rs119475040Ensembl.1
GAPO syndrome (GAPO)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
