This domain is found in Signal transducer and activator of transcription proteins (STAT) from animals. These proteins are activated in response to extracellular signals such as cytokines, growth factors and hormonal factors and translocate to the nucleus, where they bind to specific promoter sequences in target genes. This entry represents the all-helical linker domain that connects the DNA binding domain (Pfam:PF02864) and the SH2 domain (Pfam:PF00017) [1-5].

STAT proteins (Signal Transducers and Activators of Transcription) are a family of transcription factors that are specifically activated to regulate gene transcription when cells encounter cytokines and growth factors. This family represents the DNA binding domain of STAT, which has an ig-like fold. STAT proteins also include an SH2 domain Pfam:PF00017.
Flavivirus RNA-directed RNA polymerase, thumb domain
Flaviviruses produce a large polyprotein from the ssRNA genome, encoding structural proteins required for virus assembly and non-structural (NS1-5) proteins involved in replication of the viral genome [1,2,3]. This polyprotein is cleaved by viral and ...
Flaviviruses produce a large polyprotein from the ssRNA genome, encoding structural proteins required for virus assembly and non-structural (NS1-5) proteins involved in replication of the viral genome [1,2,3]. This polyprotein is cleaved by viral and cellular proteases to produce mature viral proteins. NS5 is the largest mature viral protein and contains a N-terminal methyltransferase (MTase) domain separated by a short linker from the C-terminal RNA-directed RNA polymerase domain (RdRp) that adopts a characteristic right-handed fingers-palm-thumb fold and possesses a number of short regions and motifs homologous to other RNA-directed RNA polymerases [2,3]. This entry represents the thumb domain of NS5 RdRp. NS5 binds to a the stem loop A (SLA) at the 5' extremity of Flavivirus genome and regulates translation of the viral genome [3].

This entry covers the fingers and palm domains of RNA-directed RNA polymerase (RdRp) from Flavivirus NS5. NS5 binds to a the stem loop A (SLA) at the 5' extremity of Flavivirus genome and regulates translation of the viral genome [5,6].
