Binds the poly(A) tail of mRNA (By similarity). Prevents mRNA deadenylation and confers poly(A) stability (By similarity). Stimulates the translation of mRNAs to which it is bound, acting, at least in part, with dazl (By similarity). Involved in the maternal-to-zygotic transition in early embryo via interaction with ybx1: interaction recruits pabpc1a on C5-methylcytosine (m5C)-containing maternal mRNAs, preventing their degradation (PubMed:31399345).By similarity1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
