::summary Protein-coding gene in the species Homo sapiens ::

Paired amphipathic helix protein Sin3a is a protein that in humans is encoded by the SIN3A gene.

Function

The protein encoded by this gene is a transcriptional regulatory protein. It contains paired amphipathic helix (PAH) domains, which are important for protein-protein interactions and may mediate repression by the Mad-Max complex.

Interactions

SIN3A has been shown to interact with:

CABIN1
HBP1,
HDAC1,
HDAC9,
Histone deacetylase 2,
Host cell factor C1,
IKZF1,
ING1,
KLF11,
MNT,
MXD1,
Methyl-CpG-binding domain protein 2,
Nuclear receptor co-repressor 2,
OGT,
PHF12,
Promyelocytic leukemia protein,
RBBP4,
RBBP7,
SAP130,
SAP30,
SMARCA2,
SMARCA4,
SMARCC1,
SUDS3,
TAL1, and
Zinc finger and BTB domain-containing protein 16.
