Struktura[uredi | uredi izvor]

Proizvod gena je jednoprolazni tip 1 transmembranskog proteina sa četiri egzona i vrlo velikim intronom od 85,8 kb i kodira protein koji sadrži 154 aminokiseline.^[8] Najistaknutije obilježje identificirano u proteinu je centralni, jedinstveni cisteinom i tirozinom bogati proteinski domen, na dijelu proteina koji se nalazi unutar ćelije. Utvrđeno je da je ovaj domen jako konzerviran kod nižih kičmenjaka (riba) do ljudi, ali ga nema kod bakterija i beskičmenjaka.^[6]

Svojstva i domeni[uredi | uredi izvor]

Bioinformatička analiza predvidjela je sljedeća svojstva za CYYR1:

Molekulaska težina = 16,6 kdal
Izoelektrična tačka = 8,28

Aminokiselinska sekvenca duga je 153 aminokiseline i sadrži tri domea.^[9]

Korištenjem bioinformatičkih alata utvrđeni su sljedeći domeni:

Signalni peptid^[8] – Položaj 1–29
Transmembranski domen^[8] – Položaj 62–82
Poli-prolinski domen^[8] – Položaj 144–149

Ortolozi[uredi | uredi izvor]

Višestruka poravnavanja sekvenci urađena su sa ortolozima gena CYYR1 i pokazuju da je proteinska sekvenca visoko konzervirana kod svih kičmenjaka.

U Homo sapiens nema poznatih ili predviđenih paraloga.

Interakcije[uredi | uredi izvor]

Pokazalo se da CYYR1 povećava nivo glutationa (GSH) u ćelijama kvasca kada nadopunjuje defekt u preuzimanju GSH u ćelijama kvasca kojima nedostaje Hgt1p, primarni transporter GSH kvasaca.^[11] Međutim, gen CYYR1 nije prirodno pronađen u kvascu, tako da je funkcija CYYR1 još uvijek nepoznata.
