Binds the poly(A) tail of mRNA. May be involved in cytoplasmic regulatory processes of mRNA metabolism. Can probably bind to cytoplasmic RNA sequences other than poly(A) in vivo (By similarity).
Subcellular locations: Cytoplasm
Subcellular locations: Mitochondrion matrix
Co-fractionates with mtDNA and co-immunoprecipitates with the mitochondrial poly(A) polymerase.
Expressed in fetal brain and in a range of adult tissues.
