- Y chromosome
The sex chromosome present in males of species in which the male is the heterogametic sex; generally, the sex chromosome that pairs with the X chromosome in the heterogametic sex. The Y chromosome is absent from the cells of females and present in one copy in the somatic cells of males.
- Y-shaped link assembly
The aggregation, arrangement and bonding together of a set of components to form a Y-shaped link. Two distinct protein complexes are known to be involved in proper linker assembly: the MKS complex and the NPHP complex. Improper assembly of Y-shaped links may cause malfunctioning of the transition zone as a molecular gate.
- Y-shaped link
A Y-shaped protein complex in the ciliary transition zone that connects the cilium axoneme to the ciliary necklace. Both protein sorting and protein gating occur at this point in the cilium allowing some, but not all proteins to enter the cilium.
- Y-form DNA binding
Binding to a DNA segment shaped like a Y. This shape occurs when DNA contains a region of paired double-stranded DNA on one end and a region of unpaired DNA strands on the opposite end.
