Dysbindin (Biogenesis of lysosome-related organelles complex 1 subunit 8) (BLOC-1 subunit 8) (Dysbindin-1) (Dystrobrevin-binding protein 1) (Hermansky-Pudlak syndrome 7 protein homolog) (HPS7 protein homolog) |

Null mice exhibit cognitive abnormalities including schizophrenia-related behaviors such as impaired working memory under stressful conditions. There is higher acoustic startle reactivity to stimuli. Pyramidal neurons are hypoexcitable on dopamine-2 receptor stimulation. There is reduced expression of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) and CaMKKbeta in the medial prefrontal cortex mPFC. There is increased expression levels of cell surface dopamine receptor D2 in cortical neurons. Expression levels of SYN1 are lower in both cortex and in the hippocampal formation (HF). {ECO:0000269|PubMed:15345706, ECO:0000269|PubMed:19094965, ECO:0000269|PubMed:20956979}. |
