  • noun
  • /ˈsaɪklɪn/
  • Specialized
: ciclina
  • In the 1980s and 1990s, she conducted pioneering research on cyclins, proteins that drive cells through the cell division cycle.
  • cyclin-dependent kinase
  • cyclin-dependent
  • cyclin/CDK complex

Examples

  • However, the degree to which cellular genes depend on cyclin T1 versus cyclin T2 is currently unknown.

  • Significance: This mouse model establishes the significance of this modification for the nuclear accumulation of cyclin D1-CDK4.

  • However, depending on the cyclin/CDK heterodimer targeted, the interaction shows remarkable differences.

    Academic text (2017)
  • For several years, the capability to inhibit the cyclin/CDK complexes has remained the exclusive p27 function.

    Academic text (2017)
  • First, although p27 inhibits cyclin D/CDK4 and cyclin A/CDK2 with a similar efficiency, significant changes in the enthalpy/entropy balance associated with the binding were reported.

    Academic text (2017)
  • Moreover, a recent report showed that p27 and stathmin interaction down-regulates H-Ras/MAPK and cyclin D/CDK4(6) activities.

    Academic text (2017)
  • Since p27 inhibits cyclin E(A)/CDK2 activity, the involvement of CDK2 in p27 degradation appears, at first glance, quite obscure.

    Academic text (2017)
  • p27Kip1 (hereinafter reported as p27) was identified as a protein able to bind and inhibit the activity of the cyclin E/cyclin-dependent kinase 2 (CDK2) complex 1-3.

    Academic text (2017)
  • In cancer research, scientists study how cyclin proteins regulate the cell cycle and influence tumor growth.

  • The role of cyclin in controlling cell division is crucial for understanding cancer progression.

cyclin singular
cyclins plural

Morphology

cyclin = cycle (semi-transparent) = cycl + in

The base 'cycle' is clearly present, but the suffix '-in' (a scientific/protein-forming suffix) is technical and not obvious to general learners.

Etymology

The word cyclin comes from the Greek root cycl- meaning 'circle' or 'cycle', the same root you see in cycle, and the ending -in is a common name for a protein. These proteins rise and fall in a repeating cycle, so the name helps you remember they control the cell 'cycle'.
