Characterizations

PRPF4B (Homo sapiens)
HepG2
Method: immunoprecipitation
Attachment from submitter
compliant
Caption
Immunoprecipitation was performed on nuclear extracts from the cell line HepG2 using the antibody A301-665A. Lane 1: input nuclear lysate. Lane 2: material immunoprecipitated with antibody. Lane 3: material immunoprecipitated using control IgG. Marked bands were excised from gel and subjected to analysis by mass spectrometry. Target molecular weight: 116.987.

PRPF4B (Homo sapiens)
Method: immunoprecipitation followed by mass spectrometry
exempt from standards
Caption
IP followed by mass spectrometry. Briefly, protein was immunoprecipitated from HepG2 nuclear cell lysates using the antibody A301-665A, and the IP fraction was loaded on a 10% polyacrylamide gel (NuPAGEBis-Tris Gel) and separated with an Invitrogen NuPAGE electrophoresis system. The gel was stained by ColloidialCoomassie G-250 stain, gel fragments corresponding to the bands indicated were excised. Then proteins were trypsinized using the in-gel digestion method. Digested proteins were analyzed on an Orbitrap Elite mass spectrometer (Thermo Scientific) by the nanoLC-ESI-MS/MS technique. Peptides were identified by the SEQUEST algorithm and filtered with a high confidence threshold (Peptide false discovery rate < 1%, 2 unique peptides per protein minimum, mass error < 10 ppm).
Submitter comment
SNRNP200 involves ATP binding and Poly (A) RNA binding. Both HNRNPUL1 and PRPF4B have interactions with NTRK1 (87KD), http://thebiogrid.org/114416/summary/homo-sapiens/prpf4b.html and http://thebiogrid.org/116281/summary/homo-sapiens/hnrnpul1.html, NTRK1 is not in the same gel slice with HNRNPUL1 and PRPF4B. Both ILF3 and PRPF4B have interactions with ARRB2 (46KD), http://thebiogrid.org/114416/summary/homo-sapiens/prpf4b.html and http://thebiogrid.org/109822/summary/homo-sapiens/ilf3.html, ARRB2 is not in the same gel slice with ILF3 and PRPF4B. Both ILF3 and PRPF4B have interactions with ARRB2 (46KD), http://thebiogrid.org/114416/summary/homo-sapiens/prpf4b.html and http://thebiogrid.org/109822/summary/homo-sapiens/ilf3.html, ARRB2 is not in the same gel slice with ILF3 and PRPF4B. PRPF8 and PRPF4B have interaction, http://thebiogrid.org/114416/summary/homo-sapiens/prpf4b.html. BSCL2 mainly locates in Endoplasmic reticulum membrane, involves lipid metabolism.
Reviewer comment
Though ILF3 is ranked higher than PRPF4B but as noted by the submitters, they have interaction partners in common.
