Description

This entry represents the C-terminal alpha-helical domain of Integrator complex subunit 14 (IntS14)
[1]
, a component of the integrator complex which is involved in the transcription of small nuclear RNAs (snRNA) and their 3'-box dependent processing. This complex is also involved in the 3'-end processing of the U7 snRNA, and the spliceosomal snRNAs U1 and U5
[2]
. IntS14 interacts with IntS13; both of them consist of an N-terminal VWA domain followed by a central beta-barrel domain and a C-terminal alpha-helical domain, which are connected through a linker devoid of secondary structure elements. This domain contribute to binding by packing against the beta-barrel of IntS13
[1]
.
