  • Function

    Isoform 1 is involved as a ribosomal RNA processing factor in ribosome biogenesis. Binds to tightly bent AT-rich stretches of double-stranded DNA.
    Isoform 2 binds to double-stranded DNA.
  • Tissue specificity

    Isoform 2 is much more stable than isoform 1 (at protein level). Ubiquitous. Isoform 1 and isoform 2 are expressed in kidney, liver, blood vessel, brain, mammary gland, skeletal muscle, small intestine and submandibularis. Isoform 1 transcripts are much more abundant than isoform 2 in each tissue analyzed.
  • Sequence similarities

    Belongs to the ppiC/parvulin rotamase family. PIN4 subfamily.
    Contains 1 PpiC domain.
  • Domain

    The PPIase domain enhances mitochondrial targeting.
  • Post-translational

    Phosphorylated. Isoform 1 phosphorylation occurs both in the nucleus and the cytoplasm. Isoform 1 phosphorylation at Ser-19 does not affect its PPIase activity but is required for nuclear localization, and the dephosphorylation is a prerequisite for the binding to DNA. The unphosphorylated isoform 1 associates with the pre-rRNP complexes in the nucleus.
    Isoform 2 is sumoylated by SUMO2 and SUMO3.
  • Cellular localization

    Mitochondrion. Mitochondrion matrix. Imported in a time- and membrane potential-dependent manner to the mitochondrial matrix, but without concomitant processing of the protein. Directed to mitochondria by a novel N-terminal domain that functions as non-cleavable mitochondrial targeting peptide and Nucleus > nucleolus. Cytoplasm > cytoskeleton > spindle. Cytoplasm. Colocalizes in the nucleolus during interphase and on the spindle apparatus during mitosis with NPM1.

  • Paraffin-embedded human testis tissue stained for PIN4 using ab237619 at 1/800 dilution in immunohistochemical analysis.

    After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  • HepG2 (human liver hepatocellular carcinoma cell line) cells stained for PIN4 (green) using ab237619 at 1/266 dilution in ICC/IF, followed by Alexa Fluor 488-congugated Goat Anti-Rabbit IgG (H+L) secondary antibody.

    The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. Counterstained with DAPI.
