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 Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SmESmall ribonucleoprotein particle protein SmE (SmE) encodes an RNA binding protein that functions as part of a heteroheptameric ring structure called the Sm core. This complex binds to spliceosomal small nuclear RNAs (e.g. U1, U2, U4 and U5) and helps to carry out pre-mRNA splicing. It also forms a heterotrimeric sub-complex with the products of SmF and SNRPG. (94 aa)
SmBSmall ribonucleoprotein particle protein SmB (SmB) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmD3.

Cpsf160Cleavage and polyadenylation specificity factor subunit 1; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays 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. This subunit is involved in the RNA recognition step of the polyadenylation reaction (By similarity); Belongs to the CPSF1 family. (1455 aa)
Lsm11FI05704p; Lsm11 (Lsm11) encodes one of the seven proteins that form a heptameric Sm ring in the U7 snRNP, which is a key factor involved in 3' end processing of histone pre-mRNAs. It interacts with the product of FLASH. The two interacting proteins form a biochemical platform that recruits a number of polyadenylation subunits to the U7 snRNP, including the products of Sym, Cpsf100, Cpsf73 and CstF64. (256 aa)
Lsm10Lsm10 (Lsm10) encodes a core component of the U7 snRNP complex, which functions in 3' end processing of the non-polyadenylated, replication-dependent histone mRNAs. The product of Lsm10 is part of the heptameric Sm ring complex that binds directly to U7 snRNA. It replaces the protein encoded by SmD1 in the canonical heptameric Sm protein ring that binds spliceosomal snRNAs. (141 aa)
SmD3Small ribonucleoprotein particle protein SmD3 (SmD3) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmB. They function as part of the heteroheptameric ring complex Sm core, which is involved in the formation of spliceosomal small nuclear RNPs (U1, U2, U4 and U5), which together catalyze pre-mRNA splicing. The product of SmD3 also has a function in germline specification, as it is required for localization of the product of osk to the posterior pole of the oocyte. (151 aa)
His2A:CG31618Histone H2A; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. (124 aa)
SlbpHistone RNA hairpin-binding protein; Stem-loop binding protein (Slbp) encodes a protein that plays an essential role in 3' end processing of histone pre-mRNAs into mature histone mRNAs by recruiting the product of snRNA:U7 to the pre-mRNA. (276 aa)
