Gene Information

human ... INTS1(26173)

General description

Integrator complex subunit 1 (UniProt Q8N201; also known as Int1) is encoded by the INTS1 (also known as KIAA1440, UNQ1821/PRO3434) gene (Gene ID 26173) in human. INTS1 is a large protein that is a component of the integrator complex that is involved in small nuclear RNAs U1 and U2 transcription and their 3′-box-dependent processing. During transcriptional regulation and in RNA processing, it directly binds to the C-terminal domain of the RNA polymerase II largest subunit. It has been reported that INTS1 is also involved in different cell support processes, such as the formation of a scaffold for the assembly of integrator complex. Developing INTS1 (-/-) mouse embryos show growth arrest at the early blastocyst stage and exhibit activated caspase-3 and caspase-7 that induce apoptosis within the inner cell mass of blastocyst.

Transcription by RNA polymerase II (RNAPII) is pervasive in the human genome. However, the mechanisms controlling transcription at promoters and enhancers remain enigmatic. Here, we demonstrate that Integrator subunit 11 (INTS11), the catalytic subunit of the Integrator complex, regulates transcription

RNA 3' end processing provides a source of transcriptome diversification which affects various (patho)-physiological processes. A prime example is the transcript isoform switch that leads to the read-through expression of the long non-coding RNA NEAT1_2, at the expense of the

Gene expression by RNA polymerase II (RNAPII) is tightly controlled by cyclin-dependent kinases (CDKs) at discrete checkpoints during the transcription cycle. The pausing checkpoint following transcription initiation is primarily controlled by CDK9. We discovered that CDK9-mediated, RNAPII-driven transcription is functionally
