PCF11, cleavage and polyadenylation factor subunit, homolog (S. cerevisiae) in Homo sapiens
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Size
small protein node
small nodes:
protein of unknown 3D structure
large protein node
large nodes:
some 3D structure is known or predicted
Node Color
colored protein node
colored nodes:
query proteins and first shell of interactors
non-colored protein node
white nodes:
second shell of interactors
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
database edge
from curated databases
experiment edge
experimentally determined
Predicted Interactions
neighborhood edge
gene neighborhood
fusion edge
gene fusions
cooccurrence edge
gene co-occurrence
Others
textmining edge
textmining
coexpression edge
co-expression
homology edge
protein homology

PCF11PCF11, cleavage and polyadenylation factor subunit, homolog (S. cerevisiae); Component of pre-mRNA cleavage complex II (1555 aa)    
Predicted Functional Partners:
CLP1
cleavage and polyadenylation factor I subunit 1; Polynucleotide kinase that can phosphorylate the 5’- hydroxyl groups of double-stranded RNA (dsRNA), single-stranded RNA (ssRNA), double stranded DNA (dsDNA) and double-stranded DNA-RNA hybrids. dsRNA is phosphorylated more efficiently than dsDNA, and the RNA component of a DNA-RNA hybrid is phosphorylated more efficiently than the DNA component. Appears to have roles in both tRNA splicing and mRNA 3’-end formation. Component of the tRNA splicing endonuclease complex. Phosphorylates the 5’-terminus of the tRNA 3’-exon during tRNA splicin [...] (425 aa)

POLR2A
polymerase (RNA) II (DNA directed) polypeptide A, 220kDa; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Forms the polymerase active center together with the second largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB1 is part of the core element with the cen [...] (1970 aa)

CPSF3
cleavage and polyadenylation specific factor 3, 73kDa; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3’-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Has endonuclease activity, and functions as mRNA 3’-end-processing endonuclease. Also involved in the histone 3’-end pre-mRNA processing. U7 snRNP- dependent protein that induces both the 3’-endoribonucleolytic cleavage of histone pre-mRNAs and acts as a 5’ to 3’ [...] (684 aa)

Common component of RNA polymerases I, II, and III which synthesize ribosomal RNA precursors, mRNA precursors and many functional non-coding RNAs, and small RNAs, such as 5S rRNA and tRNAs, respectively. Pol II is the central component of the basal RNA polymerase II transcription machinery. Pols are composed of mobile elements that move relative to each other.

ALYREF
Aly/REF export factor; Component of the THO subcomplex of the TREX complex. The TREX complex specifically associates with spliced mRNA and not with unspliced pre-mRNA. It is recruited to spliced mRNAs by a transcription-independent mechanism. Binds to mRNA upstream of the exon-junction complex (EJC) and is recruited in a splicing- and cap-dependent manner to a region near the 5’ end of the mRNA where it functions in mRNA export. The recruitment occurs via an interaction between ALYREF/THOC4 and the cap-binding protein NCBP1. DDX39B functions as a bridge between ALYREF/THOC4 and the THO [...] (264 aa)
