UniProt ID: Q4VBT1 |
FUNCTION: Binds free fatty acids and their coenzyme A derivatives, bilirubin, and some other small molecules in the cytoplasm. May be involved in intracellular lipid transport (By similarity). {ECO:0000250|UniProtKB:P07148}. SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P07148}. TISSUE SPECIFICITY: Expressed in the yolk syncytial layer (YSL) and subsequently in the intestinal bulb in developing embryos and larvae. In adults, expressed in the intestine. {ECO:0000269|PubMed:16857010, ECO:0000269|PubMed:19953126}. INDUCTION: By a linolenic acid-rich diet. {ECO:0000269|PubMed:19725974}. DOMAIN: Forms a beta-barrel structure that accommodates hydrophobic ligands in its interior. {ECO:0000250|UniProtKB:P07148}. MISCELLANEOUS: The zebrafish genome contains duplicated fabp1b genes (fabp1b.1 and fabp1b.2) which probably arose from a tandem gene duplication event. {ECO:0000305}. SIMILARITY: Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family. {ECO:0000255}. CAUTION: PubMed:16857010 reports that adult expression is restricted to the intestine and absent from the liver, whereas PubMed:19953126 detects expression in the liver, intestine, heart, testis, ovary, and gills. {ECO:0000305}. |
