| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | 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. Ref.9 Ref.10 |
| Subunit structure | Interacts with gelatin and type 1 collagen. Interacts with the actin cytoskeleton. Binds to the protective antigen (PA) of Bacillus anthracis. Binding does not occur in the presence of calcium. Ref.2 Ref.6 Ref.9 Ref.10 Ref.13 |
| Subcellular location | Cell membrane; Single-pass type I membrane protein. Cell projection › lamellipodium membrane; Single-pass type I membrane protein. Cell projection › filopodium membrane; Single-pass type I membrane protein. Note: At the membrane of lamellipodia and at the tip of actin-enriched filopodia. Colocalizes with actin at the base of lamellipodia. Ref.10 |
| Tissue specificity | Detected in umbilical vein endothelial cells (at protein level). Highly expressed in tumor endothelial cells. Ref.9 |
| Induction | Up-regulated in cultured angiogenic umbilical vein endothelial cells. Ref.9 |
| Domain | Binding to PA occurs through the VWA domain. |
| Involvement in disease | Defects in ANTXR1 are associated with susceptibility to hemangioma capillary infantile (HCI) [MIM:602089]. HCI are benign, highly proliferative lesions involving aberrant localized growth of capillary endothelium. They are the most common tumor of infancy, occurring in up to 10% of all births. Hemangiomas tend to appear shortly after birth and show rapid neonatal growth for up to 12 months characterized by endothelial hypercellularity and increased numbers of mast cells. This phase is followed by slow involution at a rate of about 10% per year and replacement by fibrofatty stroma. Ref.14 |
| Sequence similarities | Belongs to the ATR family. Contains 1 VWFA domain. |
| Sequence caution | The sequence BAA91707.1 differs from that shown. Reason: Erroneous initiation (Translation N-terminally extended) due to a conflict with the genome, including a frameshift. The sequence BAB15128.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |

Alternative products
| This entry describes 4 isoforms produced by alternative splicing. [Align] [Select] Note: Experimental confirmation may be lacking for some isoforms. | ||||||
| Isoform 1 (identifier: Q9H6X2-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 2 (identifier: Q9H6X2-2) The sequence of this isoform differs from the canonical sequence as follows: 365-368: EDDD → NKIK 369-564: Missing. | ||||||
| Isoform 3 (identifier: Q9H6X2-3) The sequence of this isoform differs from the canonical sequence as follows: 268-297: NEKPFSVEDTYLLCPAPILKEVGMKAALQV → SKSLQSPWVSSTSGFKEGNSHPCLPARPHT 298-564: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 4 (identifier: Q9H6X2-4) The sequence of this isoform differs from the canonical sequence as follows: 319-333: DGSILAIALLILFLL → LHKIASGPTTAACME 334-564: Missing. |

| Natural variant | 326 | 1 | A → 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.
