Editing Calcium channel (section)

== Non-selective channels permeable to calcium ==
There are several cation channel families that allow positively charged ions including calcium to pass through. These include [[P2X receptor|P2X receptors]], [[Transient receptor potential channel|Transient Receptor Potential (TRP) channels]], [[Cyclic nucleotide–gated ion channel|Cyclic nucleotide-gated (CNG) channels]], [[Acid-sensing ion channel|Acid-sensing ion channels]], and [[SOC channels]].<ref>{{Cite book |last1=Zheng |first1=Jie |url=https://www.taylorfrancis.com/books/9781003096276 |title=Textbook of Ion Channels Volume II: Properties, Function, and Pharmacology of the Superfamilies |last2=Trudeau |first2=Matthew C. |date=2023-06-06 |publisher=CRC Press |isbn=978-1-003-09627-6 |edition=1 |location=Boca Raton |language=en |doi=10.1201/9781003096276|s2cid=259784278 }}</ref> These channels can be regulated by membrane voltage potentials, ligands, and/or other cellular conditions. [[Cation channels of sperm|Cat-Sper]] channels, found in mammalian sperm, are one example of this as they are voltage gated and ligand regulated.<ref>{{Cite journal |last1=Wu |first1=Jianping |last2=Yan |first2=Zhen |last3=Li |first3=Zhangqiang |last4=Yan |first4=Chuangye |last5=Lu |first5=Shan |last6=Dong |first6=Mengqiu |last7=Yan |first7=Nieng |date=2015-12-18 |title=Structure of the voltage-gated calcium channel Ca v 1.1 complex |url=https://www.science.org/doi/10.1126/science.aad2395 |journal=Science |language=en |volume=350 |issue=6267 |pages=aad2395 |doi=10.1126/science.aad2395 |pmid=26680202 |s2cid=22271779 |issn=0036-8075|url-access=subscription }}</ref>
