Q03135 CAV1_HUMAN:

Skeletal muscle, liver, stomach, lung, kidney and heart (at protein level). Expressed in the brain.

caveolin-1 May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity. Involved in the costimulatory signal essential for T-cell receptor (TCR)- mediated T-cell activation.



Score>80(red) has high confidence and is suggested to be used for WB detection. *The prediction model is mainly based on the alignment of immunogen sequences, the results are for reference only, not as the basis of quality assurance.

Research Backgrounds


May act as a scaffolding protein within caveolar membranes. Forms a stable heterooligomeric complex with CAV2 that targets to lipid rafts and drives caveolae formation. Mediates the recruitment of CAVIN proteins (CAVIN1/2/3/4) to the caveolae. Interacts directly with G-protein alpha subunits and can functionally regulate their activity (By similarity). Involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Its binding to DPP4 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. Recruits CTNNB1 to caveolar membranes and may regulate CTNNB1-mediated signaling through the Wnt pathway (By similarity). Negatively regulates TGFB1-mediated activation of SMAD2/3 by mediating the internalization of TGFBR1 from membrane rafts leading to its subsequent degradation.


Ubiquitinated. Undergo monoubiquitination and multi- and/or polyubiquitination. Monoubiquitination of N-terminal lysines promotes integration in a ternary complex with UBXN6 and VCP which promotes oligomeric CAV1 targeting to lysosomes for degradation.

The initiator methionine for isoform 2 is removed during or just after translation. The new N-terminal amino acid is then N-acetylated.

Phosphorylated at Tyr-14 by ABL1 in response to oxidative stress.

Skeletal muscle, liver, stomach, lung, kidney and heart (at protein level). Expressed in the brain.

Subunit Structure:

Homooligomer. Interacts with GLIPR2. Interacts with NOSTRIN. Interacts with SNAP25 and STX1A (By similarity). Interacts (via the N-terminus) with DPP4; the interaction is direct. Interacts with CTNNB1, CDH1 and JUP. Interacts with PACSIN2; this interaction induces membrane tubulation (By similarity). Interacts with SLC7A9 (By similarity). Interacts with BMX and BTK. Interacts with TGFBR1. Interacts with CAVIN3 (via leucine-zipper domain) in a cholesterol-sensitive manner. Interacts with CAVIN1. Interacts with EHD2 in a cholesterol-dependent manner. Forms a ternary complex with UBXN6 and VCP; mediates CAV1 targeting to lysosomes for degradation. Interacts with ABCG1; this interaction regulates ABCG1-mediated cholesterol efflux.

(Microbial infection) Interacts with rotavirus A NSP4.


Belongs to the caveolin family.
