This complex is involved in sperm cell hyperactivation, a process needed for sperm motility, which is essential late in the preparation of sperm for fertilisation [1]. This complex requires four auxiliary subunits (beta, gamma, delta and epsilon), which play a role in channel assembly [1]. These are multidomain proteins which share a similar domain organisation. This entry represents the C-terminal domain of delta and epsilon subunits, which covers the stem domain and the transmembrane helix, which are involved in the association with the channel domain [1].
