Supplementary information

SET/TAF-I also known as Inhibitor of Protein Phosphatase 2A (I2PP2A) is a multifunctional protein with an approximate mass of 39 kDa. It is ubiquitously expressed in various human tissues including the brain liver and testis. SET/TAF-I plays a role in chromatin remodeling and gene transcription regulation by inhibiting protein phosphatase 2A (PP2A) activity. The protein interacts with nucleosome assembly and in chromatin sliding affecting the overall structure and function of chromosomal material.
Biological function summary

In the context of cellular processes SET/TAF-I functions as a histone chaperone and is a part of the nucleosome assembly complex. This protein is involved in nucleosome disassembly and assembly during DNA replication and repair and it modulates transcriptional access for various transcription factors. It regulates the acetylation of histones influencing gene expression levels. The SET/TAF-I also participates in apoptosis and autophagy demonstrating its versatility in cellular control mechanisms.

Pathways

Studies show that SET/TAF-I engages in the MAPK/ERK signaling pathway which is critical for cell cycle progression and proliferation. It is linked with other proteins such as HMGN proteins and histone deacetylases playing a substantial role in chromatin dynamics and genomic stability. Furthermore SET/TAF-I is central to the signaling pathway that maintains normal cellular functions and responds to stress signals like oxidative stress demonstrating its importance in normal cell regulation.

Abnormalities in SET/TAF-I levels link to Alzheimer's disease and acute myeloid leukemia. In Alzheimer's the protein accumulation leads to tau hyperphosphorylation an important feature of neurodegeneration influencing PP2A's role in phosphatase activity. In acute myeloid leukemia SET/TAF-I dysregulation results in altered cell proliferation and survival signaling implicating proteins like BCL-2 and downstream apoptotic regulators. This demonstrates the protein's involvement in both neurological disorders and malignancies highlighting its broader clinical significance.

General info

Function

Multitasking protein, involved in apoptosis, transcription, nucleosome assembly and histone chaperoning. Isoform 2 anti-apoptotic activity is mediated by inhibition of the GZMA-activated DNase, NME1. In the course of cytotoxic T-lymphocyte (CTL)-induced apoptosis, GZMA cleaves SET, disrupting its binding to NME1 and releasing NME1 inhibition. Isoform 1 and isoform 2 are potent inhibitors of protein phosphatase 2A. Isoform 1 and isoform 2 inhibit EP300/CREBBP and PCAF-mediated acetylation of histones (HAT) and nucleosomes, most probably by masking the accessibility of lysines of histones to the acetylases. The predominant target for inhibition is histone H4. HAT inhibition leads to silencing of HAT-dependent transcription and prevents active demethylation of DNA. Both isoforms stimulate DNA replication of the adenovirus genome complexed with viral core proteins; however, isoform 2 specific activity is higher.

Sequence similarities

Belongs to the nucleosome assembly protein (NAP) family.

Post-translational modifications

Isoform 2 is phosphorylated on Ser-15 and Ser-24.. Isoform 2 is acetylated on Lys-11.. Some glutamate residues are glycylated by TTLL8. This modification occurs exclusively on glutamate residues and results in a glycine chain on the gamma-carboxyl group (By similarity).. N-terminus of isoform 1 is methylated by METTL11A/NTM1. Mainly trimethylated (By similarity).. Isoform 2. Cleaved after Lys-176 by GZMA. The cleavage inhibits its nucleosome assembly activity and disrupts the inhibition on NME1.
