Protein attributes

Sequence length	590 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Seems to be involved in the abscisic acid (ABA) signaling pathway. Has phosphatase activity toward Ins(1,4,5)P3 and Ins(1,3,4,5)P4, but not toward Ins(1,4)P2 and Ins1P. Ref.6 Ref.7
Catalytic activity	D-myo-inositol 1,4,5-trisphosphate + H2O = myo-inositol 1,4-bisphosphate + phosphate. Ref.6 1D-myo-inositol 1,3,4,5-tetrakisphosphate + H2O = 1D-myo-inositol 1,3,4-trisphosphate + phosphate. Ref.6
Tissue specificity	Expressed ubiquitously. Ref.6
Induction	Induced by ABA at both transcript and protein levels in a specific, transient manner. Ref.7
Sequence similarities	Belongs to the inositol-1,4,5-trisphosphate 5-phosphatase type I family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: Q84MA2-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: Q84MA2-2)

The sequence of this isoform differs from the canonical sequence as follows:
     79-83: GNVIY → D

Note: May be due to a donor acceptor splice site.
