The synapsins are a family of proteins that have long been implicated in the regulation of neurotransmitter release at synapses. Specifically, they are thought to be involved in regulating the number of synaptic vesicles available for release via exocytosis at any one time. [2] .

Synapsin I, is the collective name for Synapsin Ia and Synapsin Ib, two nearly identical phosphoproteins that in humans are encoded by the SYN1 gene.

The synapsins are a family of four proteins that are the major peripheral proteins on the cytoplasmic face of synaptic vesicles. Synaptophysin is the major integral membrane protein of synaptic vesicles.

We give a comprehensive description of the molecular basis of synapsin function, as well as an overview of the more recent evidence linking mutations in the synapsin proteins to the onset of severe central nervous system diseases such as epilepsy and schizophrenia.

Synapsins (Syns) are phosphoproteins strongly involved in neuronal development and neurotransmitter release. Three distinct genes SYN1, SYN2 and SYN3, with elevated evolutionary conservation, have been described to encode for Synapsin I, Synapsin II …

Synapsins exist in all organisms endowed with a nervous system and, in mammals, are encoded by three distinct genes (SYNI, SYNII and SYNIII) located in chromosome X, 3 and 22, respectively. 16,19,24 They are composed of a mosaic of individual and shared domains, the latter of which are highly conserved during evolution (Fig. 1).

A synapsin is a phosphoprotein associated with the synaptic vesicle membrane, playing a role in the short-term regulation of neurotransmitter release. It has three genes in mammals, with variants produced through alternate splicing, and contains phosphorylation sites that are targeted by specific protein kinases.

SYN指的是Synapsin（突触蛋白），是一种神经细胞presynapse（突触前膜）的表征蛋白。 你可以理解成，在神经细胞的IFC染色中它代表了presynapse。 这里纠正一下，这是神经细胞的IFC染色（免疫荧光），而不是IHC染色（免疫组织化学）。

synapsin 定 义 一组与突触小泡相关的具有神经元特异性的磷酸蛋白质家族。几乎存在于所有的突触颗粒的表面，并且与细胞骨架结合。可以被钙调蛋白和cAMP依赖性的蛋白激酶磷酸化。人的突触蛋白A1由705个氨基酸残基组成，B1是可变剪接的产物。 应用学科

突触素（Synapsin）是一类突触小泡相关蛋白，在调节突触小泡的储存、移动和释放过程中发挥重要作用。 突触素在突触传递和突触可塑性中起关键作用。
