CABYR
Kalcij-vezujući tirozinski protein za regulaciji fosforilacije je protein koji je kod ljudi kodiran genom CABYR.[5][6][7][8]
Dužina polipeptidnog lanca je 493 aminokiseline, a molekulska masa— 52 774.
Da bi postigli sposobnost oplodnje, spermatozoidi prolaze kroz niz morfoloških i molekulskih procesa sazrijevanja, zvanih kapacitacija, koji uključuju fosforilaciju tirozinskih proteina i povećani unutarćelijski kalcij. Protein koji kodira ovaj gen lokaliziran je na glavnom komadu biča spermatozoida, zajedno sa vlaknastom ovojnicom, sa vezanjem kalcija kada se fosforilizita tokom kapacitacije. Za ovaj gen je identifikovan pseudogen na hromosomu 3. Varijante transkripta ovog gena kodiraju višestruke proteinske izoforme. Dodatni transkript i izoforme nisu u potpunosti okarakterizirani.[8]
