MARF1 (also known as Limkain-b1) is an essential protein for controlling meiosis and retrotransposon surveillance in mouse oocytes, first described as a human autoantigen localised to a subset of ABCD3 and PXF marked peroxisomes [1]. It may function both as an adaptor to recruit specific RNA targets and an effector to catalyse the specific cleavages of target RNAs [2]. MARF1 contains an N-terminal NYN domain, two central RRMs, and C-terminal OST-HTH/LOTUS domains [3,4]. This domain represents the RNA recognition motif 1 (RRM1) of MARF1.	Domain
