Protein attributes

Sequence length	1182 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Phosphatidylinositol 3-kinase homolog that regulates longevity and diapause. Could function in the development or neuroendocrine signaling of the dauer pathway. Ref.2
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol = ADP + 1-phosphatidyl-1D-myo-inositol 3-phosphate.
Developmental stage	Expressed both maternally and zygotically. Ref.2
Sequence similarities	Belongs to the PI3/PI4-kinase family. Contains 1 C2 PI3K-type domain. Contains 1 PI3K-ABD domain. Contains 1 PI3K-RBD domain. Contains 1 PI3K/PI4K domain. Contains 1 PIK helical domain.
Sequence caution	The sequence AAC47459.1 differs from that shown. Reason: Frameshift at position 32.
