The acrosome of eutherian mammals

Cell and Tissue Research, 2015
The acrosome is not just a bag of enzymes, most of which, if not all, are singly non-essential for sperm-oocyte interaction. The Golgi-derived acrosomal cap reveals some extraordinary development and structure particularities. The acrosome of eutherian spermatozoa basically consists of two parts, the anterior and equatorial segments; the present review

SNARE Complex Assembly Is Required for Human Sperm Acrosome Reaction [PDF]

Developmental Biology, 2002
Exocytosis of the acrosome (the acrosome reaction) is a terminal morphological alteration that sperm must undergo prior to penetration of the extracellular coat of the egg. Ca2+ is an essential mediator of this regulated secretory event.

Equatorin is not essential for acrosome biogenesis but is required for the acrosome reaction

Biochemical and Biophysical Research Communications, 2014
The acrosome is a specialized organelle that covers the anterior part of the sperm nucleus and plays an essential role in mammalian fertilization. However, the regulatory mechanisms controlling acrosome biogenesis and acrosome exocytosis during fertilization are largely unknown.

An organized distribution of acrosomal proteinase in rabbit sperm acrosomes

Journal of Experimental Zoology, 1975
AbstractAcrosomal proteinase was found to be present in a highly organized distribution within the acrosomes of rabbit spermatozoa by cytochemistry. This distribution consists of at least six linear loops of evenly spaced proteinase granules, which run diagonally across the flat side of the sperm head in a criss‐crossing pattern with the two most ...
