G protein pathway suppressor 2 is a protein that in humans is encoded by the GPS2 gene. [5] [6]
This gene encodes a protein involved in G protein-mitogen-activated protein kinase (MAPK) signaling cascades. When overexpressed in mammalian cells, this gene could potently suppress a RAS- and MAPK-mediated signal and interfere with JNK activity, suggesting that the function of this gene may be signal repression. The encoded protein is an integral subunit of the NCOR1-HDAC3 (nuclear receptor corepressor 1-histone deacetylase 3) complex, and it was shown that the complex inhibits JNK activation through this subunit and thus could potentially provide an alternative mechanism for hormone-mediated antagonism of AP1 (activator protein 1) function.

GPS2 (gene) has been shown to interact with:
Histone deacetylase 1 (HDAC1) is an enzyme that in humans is encoded by the HDAC1 gene.
The nuclear receptor co-repressor 1 also known as thyroid-hormone- and retinoic-acid-receptor-associated co-repressor 1 (TRAC-1) is a protein that in humans is encoded by the NCOR1 gene.
The nuclear receptor co-repressor 2 (NCOR2) is a transcriptional coregulatory protein that contains several nuclear receptor-interacting domains. In addition, NCOR2 appears to recruit histone deacetylases to DNA promoter regions. Hence NCOR2 assists nuclear receptors in the down regulation of target gene expression. NCOR2 is also referred to as a silencing mediator for retinoid or thyroid-hormone receptors (SMRT) or T3 receptor-associating cofactor 1 (TRAC-1).
Transcription factor p65 also known as nuclear factor NF-kappa-B p65 subunit is a protein that in humans is encoded by the RELA gene.
Histone deacetylase 2 (HDAC2) is an enzyme that in humans is encoded by the HDAC2 gene. It belongs to the histone deacetylase class of enzymes responsible for the removal of acetyl groups from lysine residues at the N-terminal region of the core histones. As such, it plays an important role in gene expression by facilitating the formation of transcription repressor complexes and for this reason is often considered an important target for cancer therapy.
Histone deacetylase 3 is an enzyme encoded by the HDAC3 gene in both humans and mice.
Paired amphipathic helix protein Sin3a is a protein that in humans is encoded by the SIN3A gene.
Histone deacetylase 4, also known as HDAC4, is a protein that in humans is encoded by the HDAC4 gene.

Paired amphipathic helix protein Sin3b is a protein that in humans is encoded by the SIN3B gene.
Dr1-associated corepressor is a protein that in humans is encoded by the DRAP1 gene.
Transducin (beta)-like 1X-linked, also known as TBL1X, is a protein which in humans is encoded by the TBL1X gene.
Histone deacetylase complex subunit SAP18 is an enzyme that in humans is encoded by the SAP18 gene.
F-box-like/WD repeat-containing protein TBL1XR1 is a protein that in humans is encoded by the TBL1XR1 gene. The protein encoded by this gene has sequence similarity with members of the WD40 repeat-containing protein family. The WD40 group is a large family of proteins that appear to have a regulatory function. It is believed that the WD40 repeats mediate protein–protein interactions, and members of the family are involved in signal transduction, RNA processing, gene regulation, vesicular trafficking, cytoskeletal assembly and may play a role in the control of cytotypic differentiation.
Sin3 histone deacetylase corepressor complex component SDS3 is an enzyme that in humans is encoded by the SUDS3 gene.
Origin recognition complex subunit 1 is a protein that in humans is encoded by the ORC1 gene. It is closely related to CDC6, and both are the same protein in archaea.
