| Primary Identifier | MGI:3707421 | Allele Type | Chemically induced (ENU) |
| Gene | Disc1 | Inheritance Mode | Dominant |

| Is Wild Type | false | Project Collection | RIKEN GSC ENU Project |
| description | Binding of mutant DISC1 to phosphodiesterase-4B, cAMP specific, isoform 1 (PDE4B1) is significantly reduced (p<0.001), but PDE4B activity is similar in mutant and wild-type brain extracts. (J:120634) |
| molecularNote | This mutation, identified by temperature gradient capillary electrophoresis (TGCE) heteroduplex screening for ENU-induced mutations in exon 2 of the gene, comprises a T-to-C transition resulting in replacement of leucine with proline at amino acid position 100 of the protein. Immunoblot analysis of brain extracts with an anti-DISC1 antibody followed by densitometric analysis demonstrates the presence of similar amounts of the major protein isoforms in mutant and wild-type brains. DISC1 is also similarly distributed among subcellular fractions (except the nucleus, which was not analyzed) of mutant and wild-type brains. |
