The interleukin-3 receptor (also known as CD123 antigen) is a molecule found on cells which helps transmit the signal of interleukin-3, a soluble cytokine important in the immune system.
The gene coding for the receptor is located in the pseudoautosomal region of the X and Y chromosomes.
The receptor belongs to the type I cytokine receptor family and is a heterodimer with a unique alpha chain paired with the common beta (beta c or CD131) subunit.
The gene for the alpha subunit is 40 kilobases long and has 12 exons.
The receptor, found on pluripotent progenitor cells, induces tyrosine phosphorylation within the cell and promotes proliferation and differentiation within the hematopoietic cell lines.
I am not a child now
I can take care of myself
I mustn't let them down now
Mustn't let them see me cry
I'm fine, I'm fine
I'm too tired to listen
I'm too old to believe
All these childish stories
There is no such thing as faith
And trust and pixie dust
I try
But it's so hard to believe
I try
But I can't see what you see
I try, I try, I try...
My whole world is changing
I don't know wherew to turn
I can't leave you waiting
But I can't stay and watch this city burn
Watch it burn
'Cause I try
But it's so hard to believe
I try
But I can't see what you see
I try, I try
I try and try to understand
The distance in between
The love I feel and the things I fear
And every single dream
I can finally see it
Now I have to believe
All those precious stories
All the worl is made of...
Faith, and trust... and pixie dust
So, I'll try
Because I finally believe
I'll try, cuz I can see what you see
I'll try, I'll try
I will try
I'll try...
To fly
