This entry represents the SAP domains found in the RNF34/RFFL protein family. The RNF34/RFFL protein family consists of E3 ubiquitin-protein ligases that play a crucial role in various biological processes by mediating the ubiquitin-mediated proteasomal degradation of target proteins. Members of this family are involved in the regulation of apoptosis by ubiquitinating and promoting the degradation of caspases CASP8 and CASP10. They also participate in the regulation of the tumor necrosis factor-mediated signaling pathway, mainly through the 'Lys-48'-linked polyubiquitination and degradation of RIPK1. Additionally, they have a role in the negative regulation of p53/TP53, either directly through ubiquitination or indirectly via the degradation of SFN. Some family members are implicated in metabolic regulation by targeting PPARGC1A for degradation, influencing brown fat cell metabolism, and in innate immunity by the ubiquitination of NOD1. Furthermore, the RFFL subset of proteins is involved in endocytic recycling, highlighting the diversity of functions within the family.

This is the FYVE/PHD zinc finger form E3 ubiquitin-protein ligase RNF34 and RFFL, also known as Caspase regulator 1 and 2 (CARP1/2), respectively [1]. CARP2, also termed E3 ubiquitin-protein ligase rififylin (RFFL) is a novel caspase regulator that regulates the p53 signaling pathway through degrading 14-3-3 sigma and stabilizing MDM2. CARP1 ubiquitinates the caspases CASP8 and CASP10, promoting their proteasomal degradation, to negatively regulate cell death downstream of death domain receptors in the extrinsic pathway of apoptosis [2]. It negatively regulates p53/TP53 through its direct ubiquitination and targeting to proteasomal degradation [3].
