Loss of R2D2 Proteins ROPN1 and ROPN1L Causes Defects in Murine Sperm Motility, Phosphorylation, and Fibrous Sheath Integrity1

10 Jan 2013

Abstract excerpt

The fibrous sheath (FS) is a flagellar cytoskeletal structure unique to sperm that surrounds the outer dense fibers and axoneme. Its primary components are A-kinase anchoring proteins (AKAPs) 3 and 4, which suggests that the FS affects flagellar beating via the scaffolding of signaling pathways necessary for motility. Sperm proteins ROPN1 and ROPN1L bind AKAP3. To determine the role of ROPN1 and ROPN1L in sperm...
