CC -!- FUNCTION: Calcium-sensitive protein which reversibly blocks the barbed
CC ends of actin filaments but does not sever preformed actin filaments.
CC May play an important role in macrophage function. May play a role in
CC regulating cytoplasmic and/or nuclear structures through potential
CC interactions with actin. May bind DNA. Uncapping occurs either when
CC Ca(2+) falls or when the concentration of polyphosphoinositide rises,
CC both at low and high Ca(2+).
CC -!- SUBUNIT: Interacts with NUP62. Interacts with NUTF2 and RAN; involved
CC in CAPG nuclear import. {ECO:0000250|UniProtKB:P40121}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:8293478}. Cytoplasm
CC {ECO:0000269|PubMed:8293478}. Melanosome
CC {ECO:0000250|UniProtKB:P40121}. Cell projection, lamellipodium. Cell
CC projection, ruffle. Note=In macrophages, may be predominantly
CC cytoplasmic. Nuclear localization was observed in fibroblasts. In
CC macrophages, present at the membrane-cytoplasm interface. In activated
CC macrophages, concentrated in the ruffles of the leading lamellipodia.
CC {ECO:0000269|PubMed:8293478}.
CC -!- TISSUE SPECIFICITY: Present in a large variety of tissues and is
CC particularly abundant in kidney and lung. Highly expressed in
CC macrophages (at protein level) (PubMed:8293478).
CC {ECO:0000269|PubMed:8293478}.
CC -!- DEVELOPMENTAL STAGE: Up-regulated during HL60 cell differentiation into
CC macrophages (at protein level). {ECO:0000269|PubMed:8293478}.
CC -!- PTM: Phosphorylated. Nuclear GCAP39 is more highly phosphorylated than
CC cytoplasmic GCAP39.
CC -!- SIMILARITY: Belongs to the villin/gelsolin family. {ECO:0000305}.
CC -!- CAUTION: This protein was originally thought to be a DNA-binding
CC protein with a helix-loop-helix domain. {ECO:0000305}.
