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
Your Input:
HNRNPLheterogeneous nuclear ribonucleoprotein L; This protein is a component of the heterogeneous nuclear ribonucleoprotein (hnRNP) complexes which provide the substrate for the processing events that pre-mRNAs undergo before becoming functional, translatable mRNAs in the cytoplasm. Is associated with most nascent transcripts including those of the landmark giant loops of amphibian lampbrush chromosomes. Associates, together with APEX1, to the negative calcium responsive element (nCaRE) B2 of the APEX2 promoter (589 aa)
SNRPAsmall nuclear ribonucleoprotein polypeptide A; Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. Binds preferentially to the 5’-UGCAC-3’ motif in vitro (282 aa)
NOVA2neuro-oncological ventral antigen 2; May regulate RNA splicing or metabolism in a specific subset of developing neurons (By similarity). Binds single strand RNA (492 aa)
SNRPNsmall nuclear ribonucleoprotein polypeptide N; May be involved in tissue-specific alternative RNA processing events (240 aa)
MYEF2myelin expression factor 2 (600 aa)
SRSF7serine/arginine-rich splicing factor 7; Required for pre-mRNA splicing. Can also modulate alternative splicing in vitro. Represses the splicing of MAPT/Tau exon 10 (238 aa)
PTBP3polypyrimidine tract binding protein 3 (555 aa)
HEY1hairy/enhancer-of-split related with YRPW motif 1; Downstream effector of Notch signaling which may be required for cardiovascular development. Transcriptional repressor which binds preferentially to the canonical E box sequence 5’- CACGTG-3’. Represses transcription by the cardiac transcriptional activators GATA4 and GATA6 (308 aa)
HNRNPA1L2heterogeneous nuclear ribonucleoprotein A1-like 2; Involved in the packaging of pre-mRNA into hnRNP particles, transport of poly(A) mRNA from the nucleus to the cytoplasm and may modulate splice site selection (By similarity) (320 aa)
HNRNPA1heterogeneous nuclear ribonucleoprotein A1; Involved in the packaging of pre-mRNA into hnRNP particles, transport of poly(A) mRNA from the nucleus to the cytoplasm and may modulate splice site selection. May play a role in HCV RNA replication (372 aa)
HNRNPA2B1heterogeneous nuclear ribonucleoprotein A2/B1; Involved with pre-mRNA processing. Forms complexes (ribonucleosomes) with at least 20 other different hnRNP and heterogeneous nuclear RNA in the nucleus (353 aa)
PTBP1polypyrimidine tract binding protein 1; Plays a role in pre-mRNA splicing and in the regulation of alternative splicing events. Activates exon skipping of its own pre-mRNA during muscle cell differentiation. Binds to the polypyrimidine tract of introns. May promote RNA looping when bound to two separate polypyrimidine tracts in the same pre-mRNA. May promote the binding of U2 snRNP to pre-mRNA. Cooperates with RAVER1 to modulate switching between mutually exclusive exons during maturation of the TPM1 pre-mRNA. Represses the splicing of MAPT/Tau exon 10 (557 aa)
HEY2hairy/enhancer-of-split related with YRPW motif 2; Downstream effector of Notch signaling which may be required for cardiovascular development. Transcriptional repressor which binds preferentially to the canonical E box sequence 5’- CACGTG-3’. Represses transcription by the cardiac transcriptional activators GATA4 and GATA6 (337 aa)
SRSF3serine/arginine-rich splicing factor 3; May be involved in RNA processing in relation with cellular proliferation and/or maturation (164 aa)
HNRNPA3heterogeneous nuclear ribonucleoprotein A3; Plays a role in cytoplasmic trafficking of RNA. Binds to the cis-acting response element, A2RE. May be involved in pre-mRNA splicing (378 aa)
SNRPEsmall nuclear ribonucleoprotein polypeptide E; Appears to function in the U7 snRNP complex that is involved in histone 3’-end processing. Associated with snRNP U1, U2, U4/U6 and U5 (92 aa)
SNRPBsmall nuclear ribonucleoprotein polypeptides B and B1; Appears to function in the U7 snRNP complex that is involved in histone 3’-end processing. Associated with snRNP U1, U2, U4/U6 and U5. May have a functional role in the pre-mRNA splicing or in snRNP structure. Binds to the downstream cleavage product (DCP) of histone pre-mRNA in a U7 snRNP dependent manner (By similarity) (240 aa)
PTBP2polypyrimidine tract binding protein 2; RNA-binding protein which binds to intronic polypyrimidine tracts and mediates negative regulation of exons splicing. May antagonize in a tissue-specific manner the ability of NOVA1 to activate exon selection. Beside its function in pre- mRNA splicing, plays also a role in the regulation of translation. Isoform 5 has a reduced affinity for RNA (531 aa)
