hnRNP-U Antibody- Mouse (monoclonal) Anti-hnRNP-U
The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA) These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport While all of the hnRNPs are present in the nucleus some seem to shuttle between the nucleus and the cytoplasm The hnRNP proteins have distinct nucleic acid binding properties hnRNP U is thought to be involved in the packaging of hnRNA into large ribonucleoprotein complexes During apoptosis this protein is cleaved in a caspase-dependent way

PABP Antibody- Mouse Anti-PABP
The poly(A)-binding protein (PABP) which is found complexed to the 3-prime poly(A) tail of eukaryotic mRNA is required for poly(A) shortening and translation initiation Grange et al (1987) isolated a melanoma cell cDNA encoding human PABP The predicted 633-amino acid protein contains 4 repeats of an approximately 80-amino acid unit in its N-terminal half The authors found that this repeat region is highly conserved between human and yeast PABP and is sufficient for poly(A) binding In vitro translation of the human PABP cDNA yielded a protein with an apparent molecular mass of 73 kD by SDS-PAGE Northern blot analysis indicated that PABP is expressed as a 29-kb mRNA in human melanoma cells Gorlach et al (1994) noted that each of the 4 repeats of PABP is a ribonucleoprotein (RNP) consensus sequence RNA-binding domain They determined that PABP has a pI of approximately 103 and is a very abundant stable protein Immunofluorescence studies of mammalian cells indicated that PABP is located exclusively in the cytoplasm However using both indirect immunofluorescence and tagging of PABP1 by fusion to the green fluorescent protein (GFP) Afonina et al (1998) demonstrated that PABP1 shuttles between the nucleus and cytoplasm PABP1 accumulated in the nucleus when transcription was inhibited suggesting that active transcription is required for nuclear export of PABP1

Y14 Antibody- Mouse (monoclonal) Anti-Y14
Y14 is a protein with a conserved RNA-binding motif It is preferentially associated with mRNAs produced by splicing including both nuclear mRNAs and newly exported cytoplasmic mRNAs It is thought that the protein remains associated with spliced mRNAs as a tag to indicate where introns had been present thus coupling pre- and post-mRNA splicing events Previously it was thought that two genes encode this protein RBM8A and RBM8B it is now thought that the RBM8B locus is a pseudogene Two alternative start codons result in two forms of the protein and this gene also uses multiple polyadenylation sites
