40S-ribosomni protein S15a je protein koji je kod ljudi kodiran genom RPS15A.^[5]^[6] Izvedeni ribosomski protein 15a (RPS15A) ima 130 aminokiselina (SWISS-PROT P62244). Analizom hibridnih somatskih ćelija i analizom hibridne radijacije zračenja, Kenmochi et al. (1998) mapirali su ljudski gen RPS15A na poziciji 16p hromosoma 16.^[7]

Ribosomi, organele koje kataliziraju sintezu proteina sastoje se od male 40S i velika 60S podjedinice. Zajedno se sastoje od četiri tipa RNK i približno 80 strukturno različitih proteina. Ovaj gen kodira ribosomski protein koji je komponenta 40S podjedinice. Protein pripada porodici S8P ribosomskih proteina. Nalazi se u citoplazmi. Kao što je tipsko za gene koji kodiraju ribosomske proteine, postoji više obrađenih pseudogena ovog gena raspršenih širom genoma.^[6]

Aminokiselinska sekvenca[uredi | uredi izvor]

Dužina polipeptidnog lanca je 130 aminokiselina, a molekulska težina 14.840 Da.^[8].

Molekulska genetika[uredi | uredi izvor]

Kod majke i dvije kćeri s Diamond-Blackfan anemijom-20 (DBA20), Ikeda et al. (2017) identificirali su heterozigotnu mutaciju prerade u genu RPS15A, koja je pokazala da izaziva gubitak funkcije i haploinsuficijenciju. Eksprimiranje mutacije u ćelijama ljudskog eritroida K562 pokazalo je da potiskuje proliferaciju ćelija i uzrokuje abnormalne nivoe nekoliko pre-rRNK podjedinica, što ukazuje na poremećenu preradu RNK.

Životinjski model[uredi | uredi izvor]

Ikeda et al. (2017) otkrili su da je morfolinsko mijenjanje gena rps15a u embrionima zebrica rezultiralo abnormalnostima, uključujući tanku žumanjčanu vrećicu, savijeni rep i značajno smanjenu proizvodnju eritrocita. Mutirani fenotip mogao bi se spasiti ekspresijom divljeg tipa rps15a.^[9]
