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 projectionlamellipodium membrane; Single-pass type I membrane protein. Cell projectionfilopodium 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.

VAR_053015
Natural variant3261A → 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.
