Mxi1 | Max-interacting protein 1; Transcriptional repressor. MXI1 binds with MAX to form a sequence-specific DNA-binding protein complex which recognizes the core sequence 5'-CAC[GA]TG-3'. MXI1 thus antagonizes MYC transcriptional activity by competing for MAX. Isoform Short, which lacks a segment, has a much stronger suppressive potential and associates with a SIN3 homologous protein.

Syp | Synaptophysin; Possibly involved in structural functions as organizing other membrane components or in targeting the vesicles to the plasma membrane (By similarity). Involved in the regulation of short-term and long-term synaptic plasticity; Belongs to the synaptophysin/synaptobrevin family. (314 aa) |
