How can you use “heteromeric” in a sentence? Here are some example sentences to help you improve your vocabulary:
When coexpressed with VR1, heteromeric channels composed of both types of subunits are expected to form.
For those ion channels within this superfamily for which stoichiometry has been directly examined, all have been shown to be composed of four six-transmembrane domain subunits or pseudosubunits, with auxiliary subunits sometimes present as well [ 22 ] . An initial characterization of VR1 channels expressed in Cos and CHO cells has recently revealed that, under certain conditions, they run as multimers on pseudo-native (PFO) gels, with tetramers being one of the primary bands observed [ 23 ] . Thus, like other six membrane spanning domain channels, VR1 almost certainly forms as a tetramer; whether it combines with homologous subunits to form heteromeric channels remains to be determined.
NMDA receptors are heteromeric ion channels composed of one NR1 subunit with combination of other NR2 subunits [ 4, 5, 6, 7].
Overall, these data are consistent with previous reports that endocrine cells express voltage-sensitive ion channels that can contribute to the regulation of not only resting membrane potential and cell volume, but also cell proliferation and steroidogenesis [ 12 13 16 18 21 28 29 30 31 32 33 34 35 36 37 ] . The K +currents blocked by 4-AP in pig GC are conducted by ion channels formed by heteromeric complexes of pore-forming subunits from the KCNA (also called Kv1 or Shaker) family of proteins and accessory subunits from the KCNAB (also called Kvβ) family of proteins [ 4 ] . Similar 4-AP-sensitive K +currents play a key role in transduction of mitogenic signals in a variety of cell types, and 4-AP treatment has been associated with not only growth arrest but also apoptosis [ 2 3 8 9 10 14 38 39 40 41 42 ] .
TGFβ signals through a heteromeric receptor complex of type II and type I receptor serine-threonine kinases, which activates the downstream Smad signal transduction pathway [ 7 ] . After TGFβ binding to the receptor complex, the TGFβ type II receptor kinase phosphorylates TGFβ type I receptor which inititates the downstream response by phosphorylating receptor-regulated Smads (R-Smads), such as Smad2 and Smad3.
