== Function ==
[https://www.uniprot.org/uniprot/RIDA_CAPHI RIDA_CAPHI] Catalyzes the hydrolytic deamination of enamine/imine intermediates that form during the course of normal metabolism. May facilitate the release of ammonia from these potentially toxic reactive metabolites, reducing their impact on cellular components. It may act on enamine/imine intermediates formed by several types of pyridoxal-5'-phosphate-dependent dehydratases including L-threonine dehydratase.[UniProtKB:P52758]  Also promotes endoribonucleolytic cleavage of some transcripts by promoting recruitment of the ribonuclease P/MRP complex. Acts by bridging YTHDF2 and the ribonuclease P/MRP complex. RIDA/HRSP12 binds to N6-methyladenosine (m6A)-containing mRNAs containing a 5'-GGUUC-3' motif: cooperative binding of RIDA/HRSP12 and YTHDF2 to such transcripts lead to recruitment of the ribonuclease P/MRP complex and subsequent endoribonucleolytic cleavage.[UniProtKB:P52758]

== Publication Abstract from PubMed ==
The tumour-associated antigen UK114, isolated from goat liver, belongs to the YER057c/YIL051c/YjgF protein family, which has members in both the prokaryotes and eukaryotes. The crystal structure of a mammalian representative, goat UK114, was determined, revealing a trimeric arrangement in the crystal. It was confirmed by ultracentrifugation that UK114 is a trimer in solution. These results are in agreement with the published structures of homologues from unicellular organisms, but contrast with those reported for the rat homologue of UK114, for which a dimeric quaternary structure was proposed.
