Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0003624
UniProt IDP27144
Primary gene name(s)AK4
Synonym gene name(s)AK3, AK3L1
Protein nameAdenylate kinase 4, mitochondrial
Protein functionInvolved in maintaining the homeostasis of cellular nucleotides by catalyzing the interconversion of nucleoside phosphates. Efficiently phosphorylates AMP and dAMP using ATP as phosphate donor, but phosphorylates only AMP when using GTP as phosphate donor. Also displays broad nucleoside diphosphate kinase activity. {ECO:0000255|HAMAP-Rule:MF_03170, ECO:0000269|PubMed:19073142, ECO:0000269|PubMed:19766732, ECO:0000269|PubMed:23416111}.
Subcellular locationMitochondrion matrix {ECO:0000255|HAMAP-Rule:MF_03170, ECO:0000269|PubMed:11485571, ECO:0000269|PubMed:19766732}.
