Alignment of Human CatSper voltage sensor and pore forming regions with selected L- and T-type calcium channels. (a) Voltage sensor region of CatSper human protein sequences aligned with repeats 1–4 of selected human L- and T-type calcium channels; CCAA_Human – calcium channel alpha1A (SWISSPROT O00555), CCAS_Human – calcium channel 1S (SWISSPROT Q13698) and CCAH_Human – calcium channel 1H (SWISSPROT O95180). (b) Pore selectivity region of CatSper ion channel family aligned with selected human L- and T-type calcium channels ion transport repeats.
