Meis1 | Homeobox protein Meis1; Acts as a transcriptional regulator of PAX6. Also acts as a transcriptional activator of PF4 in complex with PBX1 or PBX2. Required for hematopoiesis, megakaryocyte lineage development and vascular patterning. May function as a cofactor for HOXA7 and HOXA9 in the induction of myeloid leukemias; Belongs to the TALE/MEIS homeobox family. (465 aa) | ||||
Ophn1 | Oligophrenin-1; Stimulates GTP hydrolysis of members of the Rho family. Its action on RHOA activity and signaling is implicated in growth and stabilization of dendritic spines, and therefore in synaptic function. Critical for the stabilization of AMPA receptors at postsynaptic sites. Critical for the regulation of synaptic vesicle endocytosis at presynaptic terminals (By similarity). Required for the localization of NR1D1 to dendrites, can suppress its repressor activity and protect it from proteasomal degradation. (802 aa) |
