<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Inhibitor subunit of the major nuclear protein phosphatase-1 (PP-1). It has RNA-binding activity but does not cleave RNA and may target PP-1 to RNA-associated substrates. May also be involved in pre-mRNA splicing. Binds DNA and might act as a transcriptional repressor. Seems to be required for cell proliferation.1 Publication

Miscellaneous

A synthetic peptide, NIPP-1(191-200), is able to inhibit PP-1. Alanine substitution of Val-201 and Phe-203 in NIPP-1(191-210) prevents PP-1 binding (far-western assay) but do not affect PP-1 inhibition. Phosphorylation of Ser-199 or Ser-204 prevents PP-1 binding (far-western assay) and reduces PP-1 inhibition.

<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.
