Primary Identifier | IPR035829 | Type | Domain |
Short Name | PRY/SPRY_TRIM4 |
description | This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C terminus of TRIM4 which is also known as RING finger protein 87 (RNF87). TRIM proteins are defined by the presence of the tripartite motif RING/B-box/coiled-coil region and also known as RBCC proteins []. TRIM4 is a positive regulator of RIG-I-mediated interferon (IFN) induction. It regulates virus-induced IFN induction and cellular antiviral innate immunity by targeting RIG-I for K63-linked poly-ubiquitination []. Over-expression of TRIM4 enhances virus-triggered activation of transcription factors IRF3 and NF-kappaB, as well as IFN-beta induction []. Expression of TRIM4 differs significantly in Huntington's Disease (HD) neural cells when compared with wild-type controls, possibly impacting down-regulation of the Huntingtin (HTT) gene, which is involved in the regulation of diverse cellular activities that are impaired in Huntington's Disease (HD) cells []. |
