function: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.,PTM:Arg-518 is dimethylated, probably to asymmetric dimethylarginine.,similarity:Belongs to the polyadenylate-binding protein type-1 family.,similarity:Contains 1 PABC domain.,similarity:Contains 4 RRM (RNA recognition motif) domains.,subunit:Interacts with NFX1.,tissue specificity:Expressed at low levels in resting normal T cells; following T-cell activation, however, mRNA levels are rapidly up-regulated.,
Cytoplasm . Localized in cytoplasmic mRNP granules containing untranslated mRNAs.
Expressed at low levels in resting normal T cells; following T-cell activation, however, mRNA levels are rapidly up-regulated.
