CC -!- FUNCTION: Cross-links actin filaments (F-actin) in a calcium
CC independent manner. Induces the formation of actin aggregates.
CC Stabilizes and prevents F-actin depolymerization mediated by profilin.
CC Key regulator of actin cytoarchitecture, probably involved in cell
CC cycle, cell division, cell elongation and cytoplasmic tractus.
CC {ECO:0000269|PubMed:11123801, ECO:0000269|PubMed:11506361}.
CC -!- SUBUNIT: Interacts with F-actin. {ECO:0000269|PubMed:11123801}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC {ECO:0000269|PubMed:11506361}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=Q7G188-1; Sequence=Displayed;
CC -!- TISSUE SPECIFICITY: Constitutively expressed in roots, leaves, flowers
CC and siliques, and to lower extent in stems.
CC {ECO:0000269|PubMed:9484459}.
CC -!- DOMAIN: The actin-binding domain 1 (also called ABD1) seems to not bind
CC F-actin alone while the second actin-binding domain (ABD2) can bind F-
CC actin alone. EF-hand domain and the last 65 C-terminal amino acids are
CC not required to cross-link F-actin, but enhance the stability of the
CC binding. {ECO:0000269|PubMed:15274920, ECO:0000269|PubMed:15362112}.
CC -!- MISCELLANEOUS: Cross-links actin with a constant of dissociation of
CC 0.55 uM and stoichiometry of 4 molecules of F-actin for one molecule of
CC FIM1. {ECO:0000269|PubMed:11123801}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAB97846.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
