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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PAPD5Non-canonical poly(A) RNA polymerase PAPD5; Catalytic subunit of a TRAMP-like complex which has a poly(A) RNA polymerase activity and is involved in a post- transcriptional quality control mechanism. Polyadenylation with short oligo(A) tails is required for the degradative activity of the exosome on several of its nuclear RNA substrates. Doesn’t need a cofactor for polyadenylation activity (in vitro). Plays a role in replication-dependent histone mRNA degradation, probably through terminal uridylation of mature histone mRNAs. May play a role in sister chromatid cohesion; Belongs to the [...] (698 aa)    
Predicted Functional Partners:
SKIV2L2
Superkiller viralicidic activity 2-like 2; Component of exosome targeting complexes. Subunit of the trimeric nuclear exosome targeting (NEXT) complex, a complex that directs a subset of non-coding short-lived RNAs for exosomal degradation. Subunit of the trimeric poly(A) tail exosome targeting (PAXT) complex, a complex that directs a subset of long and polyadenylated poly(A) RNAs for exosomal degradation. The RNA exosome is fundamental for the degradation of RNA in eukaryotic nuclei. Substrate targeting is facilitated by its cofactor SKIV2L2/MTR4, which links to RNA-binding protein ada [...] (1042 aa)

ZCCHC8
Zinc finger CCHC domain-containing protein 8; Scaffolding subunit of the trimeric nuclear exosome targeting (NEXT) complex, a complex that directs a subset of non- coding short-lived RNAs for exosomal degradation. The RNA exosome is fundamental for the degradation of RNA in eukaryotic nuclei. Substrate targeting is facilitated by its cofactor SKIV2L2/MTR4, which links to RNA-binding protein adapters. May be involved in pre-mRNA splicing (Probable) (469 aa)

ZCCHC7
Zinc finger CCHC-type containing 7 (543 aa)
     
 
  0.937
POLR3GL
DNA-directed RNA polymerase III subunit RPC7-like; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Specific peripheric component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs; Belongs to the eukaryotic RPC7 RNA polymerase subunit family (218 aa)
           
  0.906
TUT1
Speckle targeted PIP5K1A-regulated poly(A) polymerase; Poly(A) polymerase that creates the 3’-poly(A) tail of specific pre-mRNAs. Localizes to nuclear speckles together with PIP5K1A and mediates polyadenylation of a select set of mRNAs, such as HMOX1. In addition to polyadenylation, it is also required for the 3’-end cleavage of pre-mRNAs- binds to the 3’UTR of targeted pre-mRNAs and promotes the recruitment and assembly of the CPSF complex on the 3’UTR of pre-mRNAs. In addition to adenylyltransferase activity, also has uridylyltransferase activity. However, the ATP ratio is higher tha [...] (912 aa)

EXOSC10
Exosome component 10; Putative catalytic component of the RNA exosome complex which has 3’->5’ exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. In the nucleus, the RNA exosome complex is involved in proper maturation of stable RNA species such as rRNA, snRNA and snoRNA, in the elimination of RNA processing by-products and non-coding ’pervasive’ transcripts, such as antisense RNA species and promoter-upstream transcripts (PROMPTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. [...] (885 aa)

MTPAP
Poly(A) RNA polymerase, mitochondrial; Polymerase that creates the 3’ poly(A) tail of mitochondrial transcripts. Can use all four nucleotides, but has higher activity with ATP and UTP (in vitro). Plays a role in replication-dependent histone mRNA degradation. May be involved in the terminal uridylation of mature histone mRNAs before their degradation is initiated. Might be responsible for the creation of some UAA stop codons which are not encoded in mtDNA (582 aa)

PAPD7
Non-canonical poly(A) RNA polymerase PAPD7; Catalytic subunit of a TRAMP-like complex which has a poly(A) RNA polymerase activity and is involved in a post- transcriptional quality control mechanism. Polyadenylation with short oligo(A) tails is required for the degradative activity of the exosome on several of its nuclear RNA substrates. Has no terminal uridylyltransferase activity, and does not play a role in replication-dependent histone mRNA degradation via uridylation; Belongs to the DNA polymerase type-B-like family (542 aa)

ADCY7
Adenylate cyclase type 7; This is a membrane-bound, calcium-inhibitable adenylyl cyclase; Adenylate cyclases (1080 aa)

ZCCHC11
Terminal uridylyltransferase 4; Uridylyltransferase that mediates the terminal uridylation of mRNAs with short (less than 25 nucleotides) poly(A) tails, hence facilitating global mRNA decay. Involved in microRNA (miRNA)-induced gene silencing through uridylation of deadenylated miRNA targets. Also acts as a suppressor of miRNA biogenesis by mediating the terminal uridylation of some miRNA precursors, including that of let-7 (pre-let-7), miR107, miR-143 and miR-200c. Uridylated miRNAs are not processed by Dicer and undergo degradation. Degradation of pre-let-7 contributes to the mainten [...] (1645 aa)
