    Summary
    This gene, through alternative splicing, encodes three different isoforms. Two of the protein isoforms encoded by this gene are specific inhibitors of type 1 serine/threonine protein phosphatases and can bind but not cleave RNA. The third protein isoform lacks the phosphatase inhibitory function but is a single-strand endoribonuclease comparable to RNase E of E. coli. This isoform requires magnesium for its function and cleaves specific sites in A+U-rich regions of RNA. [provided by RefSeq, Jul 2008]

    NCBI Reference Sequences (RefSeq)

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    1. NM_002713.3NP_002704.1  nuclear inhibitor of protein phosphatase 1 isoform gamma

      Status: REVIEWED

      Description
      Transcript Variant: This variant (3) encodes the shortest isoform (gamma, also called ARD-1). It has its first exon longer at the 3' end and lacks an internal exon as compared to that of transcript variant 1. The gamma isoform uses a different translation start site and is N-terminally truncated as compared to isoform alpha encoded by variant 1. Isoform gamma contains ribonuclease activity.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (2) is the longest transcript and has its first exon longer at the 3' end as compared to that of transcript variant 1. The resulting isoform (beta/delta) uses a different translation start site and is N-terminally truncated as compared to isoform alpha encoded by variant 1. Isoform beta/delta contains protein phosphatase inhibitory activity.
