OverviewNCBI Gene

Annexin VII is a member of the annexin family of calcium-dependent phospholipid binding proteins.The Annexin VII gene contains 14 exons and spans approximately 34 kb of DNA. An alternatively spliced cassette exon results in two mRNA transcripts of 2.0 and 2.4 kb which are predicted to generate two protein isoforms differing in their N-terminal domain. The alternative splicing event is tissue specific and the mRNA containing the cassette exon is prevalent in brain, heart and skeletal muscle. The transcripts also differ in their 3'-non coding regions by the use of two alternative poly(A) signals. Annexin VII encodes a protein with a molecular weight of approximately 51 kDa with a unique, highly hydrophobic N-terminal domain of 167 amino acids and a conserved C-terminal region of 299 amino acids. The latter domain is composed of alternating hydrophobic and hydrophilic segments. Structural analysis of the protein suggests that Annexin VII is a membrane binding protein with diverse properties, including voltage-sensitive calcium channel activity, ion selectivity and membrane fusion.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads ANXA7 as an antibody target. Whether an autoantibody or antibody against ANXA7 could matter depends on whether native ANXA7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ANXA7 is annotated at the cell surface, where native ANXA7 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.

Annotation status

The present source text does not explicitly label ANXA7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
