FABP4
fatty acid binding protein 4
Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 8 (lipid and cholesterol homeostasis). FABP4 encodes the fatty acid binding protein found in adipocytes. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands.

Protein reference (UniProt)
- Protein
Fatty acid-binding protein, adipocyte
- Function
Lipid transport protein in adipocytes. Binds both long chain fatty acids and retinoic acid. Delivers long-chain fatty acids and retinoic acid to their cognate receptors in the nucleus (By similarity).
- Subcellular location
Cytoplasm; Nucleus.

Why its pathway is in the library
Cholesterol is the obligate precursor of all steroid hormones; lipid handling sets substrate supply for steroidogenesis and neurosteroid synthesis.
Written for the whole lipid homeostasis family, not for FABP4 specifically.
Mentioned in 0 corpus records
No corpus record names FABP4 directly yet. It is in the library because it sits in a pathway the corpus tracks (Lipid homeostasis).
