HSPA1A, protein toplotnog šoka 70 kDa 1, je protein koji je kod čoveka kodiran HSPA1A genom.

Ovaj gen ne sadrži introne. On je član familije proteina toplotnog šoka 70. Zajedno s drugim proteinima toplotnog šoka, ovaj protein sprečava agregaciju postojećih proteina i posreduje savijanje novo transliranih proteina u citosolu i organelama. On takođe učestvuje u ubikvitin-proteasom putu tako što ostvaruje interakcije sa AU-bogatim elementom RNK-vezujućeg proteina 1. Ovaj gen je lociran u regionu klase III glavnog histokompatibilnostnog kompleksa, u klasteru sa dva blisko srodna gena koji kodiraju slične proteine.^[1]
