Primary Identifier | MGI:1921396 | Organism | mouse, laboratory |
Chromosome | 19 | NCBI Gene Number | 76088 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables guanyl-nucleotide exchange factor activity. Involved in dendritic cell migration; positive regulation of T cell migration; and positive regulation of establishment of T cell polarity. Acts upstream of or within immunological synapse formation and negative regulation of T cell apoptotic process. Located in cell leading edge. Is expressed in central nervous system; retina; and thymus primordium. Human ortholog(s) of this gene implicated in atopic dermatitis; bacterial infectious disease; hyper IgE recurrent infection syndrome 2; immune dysregulation-polyendocrinopathy-enteropathy-X-linked syndrome; and viral infectious disease (multiple). Orthologous to human DOCK8 (dedicator of cytokinesis 8). PHENOTYPE: Mice homozygous for inactivating mutations of this gene exhibit loss of marginal zone B cells, decrease in peritoneal B1 cells and peripheral naive T cells, failure of sustained antibody response after immunization, failure of germinal center persistence, and failure of B cell affinity maturation.
