Protein attributes

Sequence length1386 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

May be a transforming oncogene with exchange activity for CDC42 By similarity. May be a guanine-nucleotide exchange factor (GEF) for RAC1 and CDC42. Activated by the binding to subunits beta and gamma of the heterotrimeric guanine nucleotide-binding protein (G protein). Ref.5

Sequence similarities

Contains 1 DH (DBL-homology) domain.

Contains 1 PH domain.

Sequence caution

The sequence BAB15364.1 differs from that shown. Reason: Frameshift at position 84.

The sequence BAB15719.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9H7P9-1)

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: Q9H7P9-2)

The sequence of this isoform differs from the canonical sequence as follows:
     560-1368: Missing.
Note: No experimental confirmation available.
Isoform 3 (identifier: Q9H7P9-3)

The sequence of this isoform differs from the canonical sequence as follows:
     468-496: Missing.
Note: No experimental confirmation available.
