General annotation (Comments)

Function

Acts as guanine nucleotide exchange factor (GEF) for Rho GTPase. Has a critical roles in the generation of rhythmic behaviors: feeding, defecation and ovulation by dynamically regulating the concentration of intracellular calcium. Ref.1

Tissue specificity

Strong expression in the pharynx, proximal gonad, spermatheca, intestine and rectal epithelia. Ref.1

Domain

An acidic domain (AC) contains three highly conserved tyrosines that are involved in the autoinhibition of GEF activity By similarity.

Post-translational modification

GEF activity is regulated by phosphorylation on tyrosine residues.

Sequence similarities

Contains 1 CH (calponin-homology) domain.

Contains 1 DH (DBL-homology) domain.

Contains 1 PH domain.

Contains 1 phorbol-ester/DAG-type zinc finger.

Contains 1 SH2 domain.

Contains 2 SH3 domains.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform a (identifier: Q45FX5-1)

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 b (identifier: Q45FX5-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-32: Missing.
