Protein attributes
| Sequence length | 1575 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Binds to activated CDC42 and RAC1 but does not seem to stimulate their GTPase activity. Associates with calmodulin. |
| Sequence similarities | Contains 1 CH (calponin-homology) domain. Contains 3 IQ domains. Contains 1 Ras-GAP domain. Contains 1 WW domain. |
| Sequence caution | The sequence AK147360 differs from that shown. Reason: Frameshift at position 408. |
