| description | Meiosis regulator and mRNA stability factor 1 (also known as meiosis arrest female protein 1, MARF1, or Limkain-b1) was first identified as a novel peroxisomal autoantigen that co-localizes with a subset of cytoplasmic microbodies marked by ABCD3 []. Later, it was found that it is an essential regulator of oogenesis required for female meiotic progression and retrotransposon surveillance, therefore, involved in the maintenance of genomic integrity. It acts as a RNAse that efficiently cleaves ssRNAs and down-regulates RNA transcripts, either at transcriptional of post-transcriptional level [, ]. It may function both as an adaptor to recruit specific RNA targets and an effector to catalyse the specific cleavages of target RNAs. MARF1 consists of three major domains, the N-terminal NYN domain, two RNA recognition motifs (RRMs) and a C-terminal repeat of LOTUS (also known as OST-HTH) domains. |
