SH3TC2
SH3 domain and tetratricopeptide repeats-containing protein 2 is a protein that in humans is encoded by the SH3TC2 gene.[1][2] It is expressed in in the Schwann cells that wrap the myelin sheath around nerves.
Function
This gene encodes a protein with two N-terminal Src homology 3 (SH3) domains and 10 tetratricopeptide repeat (TPR) motifs, and is a member of a small gene family. The gene product has been proposed to be an adapter or docking molecule.[2]
The mouse version (orthologue) of SH3TC2 is expressed in Schwann cells, and localizes to the plasma membrane and to the perinuclear endocytic recycling compartment, consistent with a role in myelination or in axon – glial cell interactions. Mice lacking Sh3tc2 have an abnormal organization of the node of Ranvier.[3][4]
Clinical significance
Mutations in this gene result in autosomal recessive Charcot-Marie-Tooth disease type 4C, a childhood-onset neurodegenerative disease characterized by demyelination of motor and sensory neurons.[2]
