CD19
B-lymphocyte antigen CD19, also known as CD19 (Cluster of Differentiation 19), is a protein that in humans is encoded by the CD19 gene. It is found on the surface of B-cells, a type of white blood cell.
Function
Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. The CD19 gene encodes a cell surface molecule that assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
CD19 is expressed on follicular dendritic cells and B cells. In fact, it is present on B cells from earliest recognizable B-lineage cells during development to B-cell blasts but is lost on maturation to plasma cells. It primarily acts as a B cell co-receptor in conjunction with CD21 and CD81. Upon activation, the cytoplasmic tail of CD19 becomes phosphorylated, which leads to binding by Src-family kinases and recruitment of PI-3 kinase.

I know
You need
Love and understanding
Sometimes
Feel like
I can't give you more of my time
You keep on wanting me
To be there girl
But I can't be
Why you keep stressing me
When you know I'm doing my best
I keep on telling you
I do the best that I can do
How can I get through to you
Everything I do is for you
1 - You got me where you want me
Tell me what you need
Take me baby
Tell me what you want
Anywhere you wanna go is for me
You got me where you want me
I can't keep on going through these changes
The more you doubt me
You keep pusing me away girl
You keep on wanting more
I'm doing my best
I'm doing everything for you
Repeat 1
Girl, you got me yearning
Yearning to know what I'll do with love
Can you tell me what I'm doing
But I'm always saying you don't understand
I'll never leave you alone
Repeat 1
Repeat Lox
