Binds the poly(A) tail of mRNA. Appears to be an important mediator of the multiple roles of the poly(A) tail in mRNA biogenesis, stability and translation. Expressed predominantly in immature flowers but also at lower levels in mature flowers and siliques. Detected in tapetum, pollen, ovules and developing seeds. Also detected in primary inflorescences and immature siliques. A.thaliana contains 8 PABP genes. Belongs to the polyadenylate-binding protein type-1 family. Truncated N-terminus. Truncated N-terminus. Sequencing errors.
