| Primary Identifier | IPR003654 | Type | Domain |
| Short Name | OAR_dom |
| description | This 14 amino acid motif has been identified within the C-terminal region of several paired-like homeodomain (HD) containing proteins [, ]. It was named OAR domain after the initials of otp, aristaless, and rax []. Although it has been proposed that this domain could be important for transactivation and be involved in protein-protein interactions or DNA binding [, ], its function is not yet known. Some proteins known to contain a OAR domain include human RIEG, defects in which are the cause of Rieger syndrome []; human OG12X and Mus musculus (Mouse) Og12x, whose function is not yet known []; vertebrate Rax, which plays a role in the proliferation and/or differentiation of retinal cells []; Drosophila DRX, which appears to be important in brain development []; and human SHOX, encoded by the short stature homeobox-containing gene. |
