A proteína de armazón codificada neste xene é o principal compoñente das caveolas da membrana plasmática que se encontran na maioría dos tipos celulares. A proteína enlaza subunidades de integrinas á tirosina quinase FYN, un paso inicial no acoplamento de integrina á vía Ras-ERK e na promoción da progresión do ciclo celular. O xene é un supresor de tumores candidato e un regulador negativo da fervenza da Ras-p42/44 MAP quinase. Os xenes CAV1 e CAV2 están localizados un a carón do outro no cromosoma 7 e expresan proteínas colocalizadas que forman un complexo heterooligomérico estable. Utilizando codóns de iniciación alternativos no mesmo marco de lectura, as dúas isoformas que existen da caveolina 1 (alfa e beta) son codificadas por un só transcrito deste xene.[2]
A caveolina 1 presenta interaccións coas proteínas G heterotriméricas,[3]
tirosina quinases Src (Src, Lyn) e H-Ras,[4]
o colesterol,[5]
o receptor de TGF 1,[6]
a óxido nítrico sintase endotelial (eNOS),[7]
o receptor de andróxenos,[8]
a proteína precursora amiloide,[9]
a proteína das unións comunicantes, alfa 1,[10]
a óxido nítrico sintase 2A,[11] o receptor do factor de crecemento epidérmico,[12] o receptor de endotelina de tipo B,[13] a PDGFRB,[14] a PDGFRA,[14] a PTGS2,[15] o TRAF2,[16][17] o receptor de estróxenos alfa,[18] a caveolina 2,[19][20] a PLD2,[21][22] a tirosina quinase de Bruton[23] e a SCP2.[24] Todas estas interaccións son por medio dun dominio de armazón de caveolina (CSD) que hai na molécula de caveolina 1.[4] As moléculas que interaccionan coa caveolina 1 conteñen motivos de unión á caveolina (CBM).[25]
