Gene: Smpx (small muscle protein, X-linked) Mus musculus
Symbol: Smpx
Name: small muscle protein, X-linked
Description: Localizes to muscle tendon junction; myofibril; and nucleus. Is expressed in several structures, including alimentary system; heart; limb; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in X-linked deafness 4. Orthologous to human SMPX (small muscle protein X-linked); INTERACTS WITH 1,2-dimethylhydrazine; 17beta-estradiol; 2,2',4,4',5,5'-hexachlorobiphenyl.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: 1010001C09Rik; cardiac and skeletal muscle protein; chisel protein; Csl; small muscular protein; stretch-responsive skeletal muscle protein
