SS18
SS18 subunit of BAF chromatin remodeling complex
Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 18 (epigenetic regulation). Enables transcription coactivator activity. Involved in positive regulation of transcription by RNA polymerase II.

Protein reference (UniProt)
- Protein
Protein SSXT
- Function
Appears to function synergistically with RBM14 as a transcriptional coactivator. Isoform 1 and isoform 2 function in nuclear receptor coactivation. Isoform 1 and isoform 2 function in general transcriptional coactivation. Component of SWI/SNF chromatin remodeling subcomplex GBAF that carries out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner.
- Subcellular location
Nucleus.
- Tissue specificity
Fairly ubiquitously expressed. Expressed in synovial sarcomas and in other human cell lines. The fusion genes SSXT-SSX1 and SSXT-SSX2 are expressed only in synovial sarcomas.

Why its pathway is in the library
Epigenetic persistence is the leading hypothesis for why post-drug syndromes endure after the drug is gone; chromatin regulators are therefore priority candidates in any persistence mechanism.
Written for the whole epigenetic regulation family, not for SS18 specifically.
Mentioned in 0 corpus records
No corpus record names SS18 directly yet. It is in the library because it sits in a pathway the corpus tracks (Epigenetic regulation).
