Homolog člana 5 DnaJ natporodice C, također poznat i kao cisteinski string protein ili CSP jest protein koji je kod ljudi kodiran genom DNAJC5 sa hromosoma 2o.^[5] Po prvi puta opisan je 1990.^[6]

Gen[uredi | uredi izvor]

Kod ljudi, gen se nalazi na dugom kraku hromosoma 20 (20q13.33) na Watsonovom (pozitivni+om) lancu. Dug 40.867 nukleobaza, a kodirani protein ima 198 aminokiselina sa predviđenom molekulskom težinom od 22.149 kiloDa (kDa). Težina zrelog proteina je 34 kDa.

Ovaj gen je visoko konzerviran i nalazi se i kod beskičmenjaka i kod kičmenjaka. Kod ljudi, pseudogen ovog gena nalazi se na kratkom kraku hromosoma 8.

Struktura[uredi | uredi izvor]

Organizacija proteina je sljedeća:^[7]

N-terminal ima mjesto fosforilacije za protein-kinazu A
J domen (~70 aminokiselina)
regija linkera
cisteinski motiv koji se sastoji od 13–15 cisteina unutar niza od 25 aminokiselina. Jako je palmitoiliran u motivu cisteinske žice.
manje konzerviran C-terminalni domen

Tkivna distribucija[uredi | uredi izvor]

Ovaj protein je u izobilju u nervnom tkivu, karakterističnu lokaliziran na sinapsnim i klatrinom obloženim [[vezikulama. Također se nalazi na sekretornim vezikulama u endokrinim, neuroendokrinim i egzokrinim ćelijama. Ovaj protein čini ~1% sadržaja proteina sinapsnih vezikula.^[8] DNAJC5 ima ulogu u stimuliranju egzocitoza.^[9]

Funkcija[uredi | uredi izvor]

Kodirani protein je član porodice J proteina. Ovi proteini funkcionišu u mnogim ćelijskim procesima, tako što regulišu aktivnost ATPaza, 70 kDa-skih proteina toplotnog šoka (Hsp70). DNAJC5 je faktor zamjene guaninskih nukleotida za G_α proteine.^[10] CSPα ima ulogu u membranskom prometu i savijanju proteina, a pokazalo se da ima neurodegenerativna svojstva. Poznato je da ima ulogu u cistastoj fibrozi i Huntingtonovoj bolesti.^[5]

Ovaj protein je predložen kao ključni element sinapsnog molekulskog mehanizma za spašavanje sinapsnih proteina koji su se razvili stresom ovisnom o aktivnosti.^[11]^[12] Sintaksin 1A, membranski SNARE (topivi N-etilmaleimid-senzitivni faktor vezani protein receptor) kritičan za neurotransmisiju, formira kompleks sa CSPα, G- proteinom i N-tip kalcijskog kanala. Huntingtin možda može istisnuti i sintaksin 1A i CSPα iz kanala N-tipa.^[13] CSP stupa u interakciju sa proteinom senzora kalcija sinaptotagminom 9 preko svog linkerskog domena.^[14]

Protein 14 u interakciji s huntingtinom, palmitoil-transferaza, potreban je za egzocitozu i ciljanje CSP-a na sinapsnim vezikulama. Ostaci palmitoila prenose se na ostatke cisteina. Ako su ovi ostaci mutirani, ciljanje na membranu je smanjeno ili izgubljeno.^[15] Pacovski CSP formira kompleks sa Sgt (SGTA) i Hsc70 (HSPA8) koji se nalaze na površini sinapsne vezikule. Ovaj kompleks funkcionira kao ATP- ovisni šaperon koji reaktivira denaturirane supstrate. Nadalje, čini se da je kompleks Csp/Sgt/Hsc70 važan za održavanje normalne sinapse.^[7]

INjegova ekspresija se može povećati upotrebom litija.^[16] Kvercetin podstiče formiranje stabilnih dimera CSPα-CSPα.^[17]

Protein cisteinske žice povećava osjetljivost na kalcij kod egzocitoze neurotransmitera.^[18]

Interakcije[uredi | uredi izvor]

Pokazalo se da DNAJC5 reaguje sa regulatorom transmembranske provodljivosti cistadte fibroze.^[19]

Klinički značaj[uredi | uredi izvor]

Mutacije ovog gena mogu uzrokovati neuronsku ceroidnu lipofuscinozu.^[20]
