产品介绍background:
The scaffolding protein encoded by this gene is the main component of the caveolae plasma membranes found in most cell types. The protein links integrin subunits to the tyrosine kinase FYN, an initiating step in coupling integrins to the Ras-ERK pathway and promoting cell cycle progression. The gene is a tumor suppressor gene candidate and a negative regulator of the Ras-p42/44 MAP kinase cascade. CAV1 and CAV2 are located next to each other on chromosome 7 and express colocalizing proteins that form a stable hetero-oligomeric complex. By using alternative initiation codons in the same reading frame, two isoforms (alpha and beta) are encoded by a single transcript from this gene. [provided by RefSeq].

Function:
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. 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.

Subunit:
Homooligomer. Interacts with GLIPR2, NOSTRIN, SNAP25 and syntaxin. Interacts with rotavirus A NSP4. Interacts (via the N-terminus) with DPP4; the interaction is direct. Interacts with CTNNB1, CDH1 and JUP. Interacts with BMX and BTK.

Subcellular Location:
Golgi apparatus membrane;Peripheral membrane protein. Cell membrane; Peripheral membrane protein. Membrane, caveola; Peripheral membrane protein. Membrane raft. Note=Colocalized with DPP4 in membrane rafts. Potential hairpin-like structure in the membrane. Membrane protein of caveolae.

Tissue Specificity:
Expressed in muscle and lung, less so in liver, brain and kidney.

Post-translational modifications:
The initiator methionine for isoform Beta 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.

DISEASE:
Defects in CAV1 are the cause of congenital generalized lipodystrophy type 3 (CGL3) [MIM:612526]; also called Berardinelli-Seip congenital lipodystrophy type 3 (BSCL3). Congenital generalized lipodystrophies are autosomal recessive disorders characterized by a near absence of adipose tissue, extreme insulin resistance, hypertriglyceridemia, hepatic steatosis and early onset of diabetes.

Similarity:
Belongs to the caveolin family.

信号传导（Signaling Intermediates）
Caveolin-1（小凹蛋白）是细胞生长相关信号途径及肿瘤发生发展过程中重要的抑制因子，Caveolae是细胞膜内的特殊膜结构，参与包括细胞的分子运输、细胞粘附和信号转导在内的多种细胞活动。Caveolin-1是Caveolae中重要的结构蛋白，抑制细胞生长，与多种人类肿瘤发生发展相关的信号分子相互作用。Caveolin在信号转导的整合中起支架蛋白的作用。Caveolin构成了一个蛋白家族，他们是细胞质膜中发夹样结构域的主要结构成分。Caveolin在信号转导的整合中起支架蛋白的作用。至今已经鉴定了3种Caveolin （Caveolin-1、2 和3），它们具有不同的组织分布。Caveolin-1涉及乳腺上皮细胞增生的发病机制。该抗体可识别α和β型Caveolin-1。
