He is mentioned in the account of Bishop Israel of Caucasian Albania, who travelled to Alp Ilutuer's court.
During his stay in the land of Huns in 681—682, Israel condemned their pagan beliefs and practices and preached Christianity.
His converts offered him to establish and lead a patriarchate there through a special request sent by Alp Iluetuer himself to Eliezer, the Catholicos of Caucasian Albania.
However, the request was turned down due to Israel already having been assigned a congregation in Mets Kolmanķ.
Therefore, it is unclear whether Alp Ilutuer is a proper name, a title, or a combination of the two.
