Son Gene Summary [Rat]
Predicted to enable RNA binding activity and RS domain binding activity. Predicted to be involved in mRNA processing; negative regulation of apoptotic process; and regulation of mRNA splicing, via spliceosome. Predicted to be located in nuclear speck. Human ortholog(s) of this gene implicated in ZTTK syndrome and congenital anomalies of kidney and urinary tract syndrome with or without hearing loss, abnormal ears, or developmental delay. Orthologous to human SON (SON DNA and RNA binding protein). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Son often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- G-patch domain
- Double-stranded RNA binding motif
