Sex-determining region Y protein聽(SRY), or聽testis-determining factor聽(TDF)
Sex-determining region Y protein (SRY), or testis-determining factor (TDF), is a DNA-binding protein (also known as gene-regulatory protein/transcription factor) encoded by the SRY gene that is responsible for the initiation of male sex determination in therian mammals (placental mammals and marsupials). SRY is an intronless sex-determining gene on… Read more.

Agrin聽is a large聽chimeric proteoglycan, a heparan sulfate and chondroitin proteoglycan,聽whose best-characterised role is in the development of the聽neuromuscular junction聽during聽embryogenesis
Agrin was originally found in the electric organ of Tarpedo california and in the basal lamina at the neuromuscular junction as a protein that directs the aggregation of acetylcholine receptors (AChR) and acetylcholinesterase (AChE) at synaptic sites. Tetronarce californica also known as… Read more.
