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 …

SRY基因（sex-determining region of Y-chromosome，全称：Y染色体性别决定区），又名睪丸決定因子，（英語：Testis-determining factor，簡稱TDF）是人体Y染色体上的一段基因片段，该基因是决定男性睾丸发育的主要基因。存在于Y染色体的短臂末端上。

SRY基因，雄性的性别决定基因，指Y染色体上具体决定生物雄性性别的基因片段。人的SRY基因位于Yp11.3，只含有一个外显子，没有内含子，转录单位长约1.1kb，编码一个204氨基酸的蛋白质。

“sry”是什么意思？ 人类决定性别的基因，集中于第23对染色体上，也就是我们所说的性染色体，男性的是XY染色体，而女性的则是XX染色体，男性与女性最大的差别，就在于性染色体的不同，由此产生了性别的分化，男性Y染

2024年12月25日 · SRY (Sex Determining Region Y) is a Protein Coding gene. Diseases associated with SRY include 46,Xx Sex Reversal 1 and 46,Xy Sex Reversal 1. Among its related pathways are Mammalian disorder of sexual development and Signaling by WNT.

SRY (which stands for sex-determining region Y gene) is found on the Y chromosome. In the cell, it binds to other DNA and in doing so distorts it dramatically out of shape. This alters the properties of the DNA and likely alters the expression of a …

The SRY gene provides instructions for making a protein called the sex-determining region Y protein. This protein is involved in male-typical sex development, which usually follows a certain pattern based on an individual's chromosomes. People usually have 46 …

2025年2月8日 · This intronless gene encodes a transcription factor that is a member of the high mobility group (HMG)-box family of DNA-binding proteins. This protein is the testis-determining factor (TDF), which initiates male sex determination.

The gene SRY (sex determining region of the Y), located at the distal region of the short arm of the Y chromosome, is necessary for male sex determination in mammals. SRY initiates the cascade of steps necessary to form a testis from an undifferentiated gonad.

除了染色体组成外，部分的单个基因也会决定人类的性别表现，其中最重要的性别决定基因即为——sry。 SRY基因 位于Y染色体p11.2区域，该基因编码一个转录调控因子，决定着男性性别发育的起始。
