Abstract

The homologous repeats of annexin tetrads are believed to have originated by successive duplication and fusion from a putative monomeric precursor, but neither the nature of their ancestor nor the events leading to the formation of different subfamilies have been elucidated. We have performed molecular phylogenetic analysis of aligned annexin nucleotide and amino acids sequences to characterize subfamily branching, to delineate the temporal order of appearance of individual repeat units, and to gain insight into the origin and nature of the primordial unit. All extant annexins appear to have a common tetrad precursor that may have originated from a progenitor unit resembling repeat 3, followed by the generation of repeats 4, 1, and 2 from a more evolved progenitor with subsequent fusion. Repeat sequences of the earliest human annexins VII and XIII were used to identify alpha-giardin genes as primitive homologues from the unicellular protozoan Giardia lamblia, which diverged from eukaryote lineage 1-1.5 billion yr ago. The significant homology between alpha-giardins and annexins suggested that the cell membrane adhesive role of these proteins may be a common, fundamental property of the annexin C-terminal core region. Purported annexin VII of Dictyostelium discoideum was reclassified as new annexin XIV, three Caenorhabditis elegans genes were assigned to new subfamilies XV, XVI, and XVII, and plant annexin XVIII from Medicago sativa was among the earliest diverging subfamilies. Annexins I and II were found to be closely related, but analysis of protein mutation rates confirmed that the former is evolving up to three times more rapidly. The inclusion of early phyla in annexin taxonomy provides a useful basis for assessing the structural and functional changes associated with annexin evolution.

  • The alpha-giardins in Giardia were the first annexins from a protozoan eukaryote to be described.

    “The alpha-giardins in Giardia were the first annexins from a protozoan eukaryote to be described (31–33).”

    From Comparative Cell Biology and Evolution of Annexins in Diplomonads (2016) · cites this paper as [33]

    The paper identifies α-giardins from the protozoan Giardia lamblia as primitive annexin homologues (p. 1) and assigns them to annexin subfamilies XIX and XX (Discussion, p. 9). It does not establish that they were the first protozoan annexins described; “most primitive known” refers to evolutionary position, not publication order. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
