INT4 also known as Intracellular Neutral Thiol Enzyme 4 is a relatively small protein with a mass of around 28 kDa. This protein occurs mainly within intracellular compartments including the cytosol and certain organelles. It exhibits enzymatic activity involved in redox reactions making it important in cellular antioxidant defense. Although specific data on its exact tissue distribution is still under study INT4 tends to be active in tissues with high oxidative stress susceptibility.
Biological function summary

INT4 plays a significant role in cellular homeostasis and response to oxidative stress. This protein acts alone without forming large complexes. Its main function centers on maintaining the redox balance within cells which protects cellular components from oxidative damage. By modulating levels of reactive oxygen species INT4 contributes to the preservation of cellular integrity and function.

Pathways

INT4 is an essential component of the cellular redox-regulating pathways. It interacts closely with proteins involved in the glutathione system an important antioxidant pathway tasked with detoxifying reactive species and maintaining the cellular redox state. Additionally associations with the thioredoxin pathway suggest a wider role in protecting cells from oxidative stress by converting reactive oxygen and nitrogen species into less harmful forms.

Research establishes a connection between aberrant INT4 activity and Alzheimer's disease as well as Parkinson's disease. Both conditions involve oxidative stress and neurodegeneration suggesting that INT4's antioxidant function might influence disease progression. Changes in INT4 expression or function could potentially interact with other proteins like tau and alpha-synuclein which play roles in the pathology of these diseases. Understanding these interactions might offer insights into therapeutic strategies targeting oxidative damage in neurodegenerative diseases.

General info

Function

Component of the integrator complex, a multiprotein complex that terminates RNA polymerase II (Pol II) transcription in the promoter-proximal region of genes (PubMed : 29471365, PubMed : 33243860, PubMed : 33548203, PubMed : 38570683). The integrator complex provides a quality checkpoint during transcription elongation by driving premature transcription termination of transcripts that are unfavorably configured for transcriptional elongation : the complex terminates transcription by (1) catalyzing dephosphorylation of the C-terminal domain (CTD) of Pol II subunit POLR2A/RPB1 and SUPT5H/SPT5, (2) degrading the exiting nascent RNA transcript via endonuclease activity and (3) promoting the release of Pol II from bound DNA (PubMed : 33243860, PubMed : 38570683). The integrator complex is also involved in terminating the synthesis of non-coding Pol II transcripts, such as enhancer RNAs (eRNAs), small nuclear RNAs (snRNAs), telomerase RNAs and long non-coding RNAs (lncRNAs) (PubMed : 16239144). Within the integrator complex, INTS4 acts as an scaffold that links INTS9 and INTS11 (PubMed : 29471365, PubMed : 33548203). Mediates recruitment of cytoplasmic dynein to the nuclear envelope, probably as component of the integrator complex (PubMed : 23904267).
