      DescriptionRIPAb+™ PUM1 Antibody
      OverviewRIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA-binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation.
      PUM1 has been shown to bind an mRNA sequence known as Nanos response element. It is found in heart, brain, muscle, kidney, stomach and intestine. PUM proteins play an active role in the sustainability of mitotic stem cell proliferation and the regulation of cell development and differentiation.

      Background InformationWithin the mammalian genome are two genes belonging to a family of housekeeping genes known as PUF. These genes are known as PUM1 and PUM2. PUF proteins are characterized by having a C-terminal RNA-binding domain called the Pumilio homolog domain, which affects the stability of mRNA and translation by binding the 3’-UTR of mRNA targets. PUM plays an active role in the sustainability of mitotic stem cell proliferation and the regulation of cell development and differentiation. Very little has been discovered about the specific role for PUM1. However it has been shown to bind an mRNA sequence known as Nanos response element and to interact with RNA. PUM1 is found in heart, brain, muscle, kidney, stomach and intestine. It is not expressed in putamen, hippocampus, medulla oblangata, corpus collasum, cerebellum and caudate nucleus.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the PUF family, evolutionarily conserved RNA-binding proteins related to the Pumilio proteins of Drosophila and the fem-3 mRNA binding factor proteins of C. elegans. The encoded protein contains a sequence-specific RNA binding domain comprised of eight repeats and N- and C-terminal flanking regions, and serves as a translational regulator of specific mRNAs by binding to their 3' untranslated regions. The evolutionarily conserved function of the encoded protein in invertebrates and lower vertebrates suggests that the human protein may be involved in translational regulation of embryogenesis, and cell development and differentiation. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: Sequence-specific RNA-binding protein that regulates translation and mRNA stability by binding the 3'-UTR of mRNA targets. May be required to support proliferation and self-renewal of stem cells By similarity.

      SUBUNIT STRUCTURE: Binds in a sequence-specific manner to the 3'-UTR of some mRNAs.

      SUBCELLULAR LOCATION: Cytoplasm Probable.

      TISSUE SPECIFICITY: Expressed in brain, heart, kidney, muscle, intestine and stomach. Not expressed in cerebellum, corpus callosum, caudate nucleus, hippocampus, medulla oblongata and putamen. Expressed in all fetal tissues tested.

      INDUCTION: Strongly down-regulated in keratinocytes upon ultraviolet B radiation.

      DOMAIN: The pumilio repeats mediate the association with RNA by packing together to form a right-handed superhelix that approximates a half donut. The number as well as the specific sequence of the repeats determine the specificity for target mRNAs.

      SEQUENCE SIMILARITIES: Contains 1 PUM-HD domain.

      Contains 8 pumilio repeats.
      Molecular Weight~120 kDa.
      UniProtKB/Swiss-Prot Q14671 (PUM1_HUMAN) entry describes 2 isoforms produced by alternative splicing: Isoform 1 at ~126 kDa and Isoform 2 at ~124 kDa.
