Six5 is required for spermatogenic cell survival and spermiogenesis.
Myotonic dystrophy 1 (DM1) is a multi-system disorder characterized by endocrine defects that include testicular and tubular atrophy, oligospermia, Leydig cell hyperproliferation and increased follicle stimulating hormone (FSH) levels. DM1 results from a CTG expansion that causes transcriptional silencing of the flanking SIX5 allele. Loss of Six5 results in male sterility and a progressive decr...
متن کاملIQ Motif-Containing G (Iqcg) Is Required for Mouse Spermiogenesis
Spermiogenesis in mammals is the process by which the newly formed products of meiosis, haploid spermatids, undergo a dramatic morphological transformation from round cells into flagellated spermatozoa. The underlying genetic control of spermiogenesis is complicated and not well-characterized. We have used forward genetic screens in mice to illuminate the mechanisms of spermatozoon development....
متن کاملCHD5 is required for spermiogenesis and chromatin condensation
Haploid spermatids undergo extensive cellular, molecular and morphological changes to form spermatozoa during spermiogenesis. Abnormalities in these steps can lead to serious male fertility problems, from oligospermia to complete azoospermia. CHD5 is a chromatin-remodeling nuclear protein expressed almost exclusively in the brain and testis. Male Chd5 knockout (KO) mice have deregulated spermat...
متن کاملRIM-BP3 is a manchette-associated protein essential for spermiogenesis.
During spermiogenesis, round spermatids are converted into motile sperm in mammals. The mechanisms responsible for sperm morphogenesis are poorly understood. We have characterized a novel protein, RIM-BP3, with a specialized function in spermatid development in mice. The RIM-BP3 protein is associated with the manchette, a transient microtubular structure believed to be important for morphogenes...
متن کاملG-protein-coupled receptor kinase interacting protein-1 is required for pulmonary vascular development.
BACKGROUND The G-protein-coupled receptor kinase interacting protein-1 (GIT1) is a multidomain scaffold protein that participates in many cellular functions including receptor internalization, focal adhesion remodeling, and signaling by both G-protein-coupled receptors and tyrosine kinase receptors. However, there have been no in vivo studies of GIT1 function to date. METHODS AND RESULTS To d...
