NARF, HSD-4, STRIN, hNARF, E3 ubiquitin-protein ligase RNF138, Nemo-like kinase-associated RING finger protein, NLK-associated RING finger protein, RING finger protein 138, RNF138, HSD4
E3 ubiquitin-protein ligase. Together with NLK, involved in the ubiquitination and degradation of TCF/LEF. Also exhibits auto-ubiquitination activity in combination with UBE2K. May act as a negative regulator in the Wnt/beta-catenin-mediated signaling pathway.
