To know the function of the Ca2+ channel containing α12.3 (α1E) subunit (Cav2.3 channel) in spermatozoa, we analyzed Ca2+ transients and sperm motility using a mouse strain lacking Cav2.3 channel. The averaged rising rates of Ca2+ transients induced by α-D-mannose-bovine serum albumin in the head region of Cav2.3-/- sperm were significantly lower than those of Cav2.3+/+ sperm. A computer-assisted sperm motility assay revealed that straight-line velocity and linearity were greater in Cav2.3-/- sperm than those in Cav2.3+/+ sperm. These results suggest that the Cav2.3 channel plays some roles in Ca2+ transients and the control of flagellar movement.
