SH3TC2
Protein 2 SH3 domena i tetratrikopeptidnih ponavljanja je protein koji je kod ljudi kodiran genom SH3TC2 sa hromosoma 5.[5][6] Vjeruje se da je eksprimiranu Schwannovim ćelijama koje čine mijelinski omotač oko živaca.

Funkcija
urediOvaj gen kodira protein s dva N-terminala Src homologije 3 (SH3) domena i 10 ponavljanja tetratrikopeptida (TPR), te je član male porodice gena. Predloženo je da je genski proizvod adapter ili molekula za sidrenje.[6]
Veruje se da je mišja verzija (ortolog) SH3TC2 eksprimirana u Schwannovim ćelijama. Označeni protein nalazi se na plazmamembrani i u perijedarnom odjeljku za recikliranje endocita. Miševi kojima nedostaje Sh3tc2 imaju abnormalnu organizaciju Ranvijerove čvorove u skladu s idejom da bi protein mogao imati ulogu u mijelinizaciji ili u interakcijama akson – glijine ćelije.[8][9]
Klinički značaj
urediMutacije u ovom genu rezultiraju autosomno recesivnom Charcot-Marie-Toothova bolešću tipa 4C, neurodegenerativnom bolešću u djetinjstvu koju karakterizira demijelinizacija motornih i senzornih neurona.[6]
