ELAPOR1 mediated vesicle traffic is required for acrosome biogenesis and male fertility in mice [PDF]
Spermiogenesis is the post-meiotic differentiation and morphological change of the haploid spermatids. Acrosome biogenesis is one of the key events of spermiogenesis, which generates a specialized membranous organelle crucial for shaping the balanced ...

Protein disulfide isomerase A6 (PDIA6) is essential for acrosome biogenesis and male fertility in mice [PDF]
Background The family of protein disulfide isomerases (PDIs) are thiol oxidoreductases located predominantly in the endoplasmic reticulum that catalyze thiol-disulfide exchange for normal protein folding.

ELAPOR1 is a copper-dependent tethering factor driving proacrosomal vesicle fusion during acrosome biogenesis [PDF]
The acrosome is a crucial organelle essential for sperm function and male fertility. During acrosome biogenesis, numerous proacrosomal vesicles (PAVs) are transported to the concave region of the nuclear membrane and fuse to form the acrosome.

PFN4 is required for manchette development and acrosome biogenesis during mouse spermiogenesis.
ABSTRACT Profilin 4 (Pfn4) is expressed during spermiogenesis and localizes to the acrosome-acroplaxome-manchette complex. Here, we generated PFN4-deficient mice, with sperm displaying severe impairment in manchette formation. Interestingly, HOOK1 staining suggests that the perinuclear ring is established; however, ARL3 staining is ...

Acrosome biogenesis: Revisiting old questions to yield new insights. [PDF]
The acrosome is a unique membranous organelle located over the anterior part of the sperm nucleus that is highly conserved throughout evolution. This acidic vacuole contains a number of hydrolytic enzymes that, when secreted, help the sperm penetrate the egg's coats.

Abstract Asthenoteratospermia is a common cause of male infertility. Recent studies have revealed that CFAP65 mutations lead to severe asthenoteratospermia due to acrosome hypoplasia and flagellum malformations. However, the molecular mechanism underlying CFAP65-associated sperm malformation is largely unclear.

Vps13b is required for acrosome biogenesis through functions in Golgi dynamic and membrane trafficking. [PDF]
The sperm acrosome is a lysosome-related organelle that develops using membrane trafficking from the Golgi apparatus as well as the endolysosomal compartment. How vesicular trafficking is regulated in spermatids to form the acrosome remains to be elucidated. VPS13B, a RAB6-interactor, was recently shown involved in endomembrane trafficking.
