Protein Information (annotations from UniProt)

Database IDHIV0002000
UniProt IDP22736
Primary gene name(s)NR4A1
Synonym gene name(s)GFRP1, HMR, NAK1
Protein nameNuclear receptor subfamily 4 group A member 1
Protein functionOrphan nuclear receptor. May act concomitantly with NURR1 in regulating the expression of delayed-early genes during liver regeneration. Binds the NGFI-B response element, NBRE 5'-AAAAGGTCA-3', By similarity. May inhibit NF-kappa-B transactivation of IL2. Participates in energy homeostasis by sequestrating the kinase STK11 in the nucleus, thereby attenuating cytoplasmic AMPK activation. {ECO:0000250, ECO:0000269|PubMed:15466594, ECO:0000269|PubMed:22983157}.
