  • Adhesion G protein-coupled receptors (adhesion GPCRs) are a class of 33 human protein receptors with a broad distribution in embryonic and larval cells, cells of the reproductive tract, neurons, leukocytes, and a variety of tumours. Adhesion GPCRs are found throughout metazoans and are also found in single-celled colony forming choanoflagellates such as Monosiga brevicollis and unicellular organisms such as Filasterea. The defining feature of adhesion GPCRs that distinguishes them from other GPCRs is their hybrid molecular structure. The extracellular region of adhesion GPCRs can be exceptionally long and contain a variety of structural domains that are known for the ability to facilitate cell and matrix interactions. Their extracellular region contains the membrane proximal GAIN (GPCR-Autoproteolsis INducing) domain. Crystallographic and experimental data has shown this structurally conserved domain to mediate autocatalytic processing at a GPCR-proteolytic site (GPS) proximal to the first transmembrane helix. Autocatalytic processing gives rise to an extracellular (α) and a membrane-spanning (β) subunit, which are associated non-covalently, resulting in expression of a heterodimeric receptor at the cell surface.Ligand profiles and in vitro studies have indicated a role for adhesion GPCRs in cell adhesion and migration. Work utilizing genetic models confined this concept by demonstrating that the primary function of adhesion GPCRs may relate to the proper positioning of cells in a variety of organ systems. Moreover, growing evidence implies a role of adhesion GPCRs in tumour cell metastasis. Formal G protein-coupled signalling has been demonstrated for a number for adhesion GPCRs, however, the orphan receptor status of many of the receptors still hampers full characterisation of potential signal transduction pathways. In 2011, the adhesion GPCR consortium was established to facilitate research of the physiological and pathological functions of adhesion GPCRs. (en)
  • GPCR adhesi (adhesion G protein-protein-coupled receptor) adalah kelas 33 reseptor protein manusia dengan distribusi yang luas di sel embrio dan larva, sel-sel dari saluran reproduksi, neuron, leukosit, dan berbagai tumor. GPCR adhesi ditemukan di seluruh metazoan dan juga ditemukan di bersel tunggal koloni choanoflagellatea seperti Monosiga brevicollis dan organisme uniseluler seperti Filasterea. Fitur GPCR adhesi yang membedakan mereka dari GPCR lainnya adalah struktur molekul hibrida. Wilayah ekstraseluler GPCR adhesi dapat menjadi sangat panjang dan mengandung berbagai domain struktural yang dikenal karena kemampuannya untuk memfasilitasi interaksi sel dan matriks ekstraseluler. Wilayah ekstraseluler mengandung membran proksimal domain GAIN (GPCR-Autoproteolsis INducing). Data kristalografi dan eksperimental telah menunjukkan domain struktural dilestarikan ini untuk memperantarai proses autokataliktik pada GPCR-proteolytic site (GPS) ke transmembran heliks pertama. Proses autokatalitik menimbulkan suatu ekstraseluler (α) dan (β) subunit membentang membran, yang berhubungan non-kovalen, sehingga ekspresi reseptor heterodimerik di permukaan sel. Profil ligan dan dalam studi in vitro telah menunjukkan peran GPCR adhesi dalam adhesi dan migrasi sel. Studi memanfaatkan model genetik dibatasi konsep ini dengan menunjukkan bahwa fungsi utama dari GPCR adhesi mungkin berhubungan dengan posisi yang tepat dari sel-sel dalam berbagai sistem organ. Selain itu, bukti yang berkembang menyiratkan peran GPCR adhesi dalam metastasis sel tumor. Pensinyalan GPCR adhesi telah ditunjukkan untuk sejumlah adhesi GPCR, namun status reseptor orphan dari banyak reseptor masih menghambat karakterisasi penuh jalur transduksi sinyal potensial. Saat ini telah ada penamaan resmi sistematika dari GPCR adhesi. Pada tahun 2011, sebuah konsorsium ilmuwan internasional didirikan untuk memfasilitasi penelitian ke fungsi fisiologis dan patologis GPCR adhesi yaitu konsorsium GPCR adhesi . (in)
