fs(1)Yb

Drosophila melanogaster

female sterile (1) Yb (fs(1)Yb) encodes a protein involved in maintenance of the germ-line stem cell population during oogenesis.

BoYb

Drosophila melanogaster

Brother of Yb (BoYb) encodes a putative RNA helicase in the TDRD12 family and is predicted to have a role in piRNA biogenesis, specifically in ovarian germline cells.

SoYb

Drosophila melanogaster

Sister of Yb (SoYb) encodes a putative RNA helicase in the TDRD12 family. It has an essential role in primary piRNA biogenesis in ovarian somatic cells and is predicted to also have a role in germline piRNA biogenesis.

Nf-YB

Drosophila melanogaster

Nuclear factor Y-box B (Nf-YB) encodes a subunit of the nuclear transcription factor Y, which binds to the CCAAT box regulatory sequence. It regulates gene transcription and is involved in eye and thorax development.
