Myosin
Myosins (/ˈmaɪəsᵻn, -oʊ-/) comprise a family of ATP-dependent motor proteins and are best known for their role in muscle contraction and their involvement in a wide range of other motility processes in eukaryotes. They are responsible for actin-based motility. The term was originally used to describe a group of similar ATPases found in the cells of both striated muscle tissue and smooth muscle tissue. Following the discovery by Pollard and Korn (1973) of enzymes with myosin-like function in Acanthamoeba castellanii, a large number of divergent myosin genes have been discovered throughout eukaryotes. Thus, although myosin was originally thought to be restricted to muscle cells (hence myo-(s) + -in), there is no single "myosin" but rather a huge superfamily of genes whose protein products share the basic properties of actin binding, ATP hydrolysis (ATPase enzyme activity), and force transduction. Virtually all eukaryotic cells contain myosin isoforms. Some isoforms have specialized functions in certain cell types (such as muscle), while other isoforms are ubiquitous. The structure and function of myosin is strongly conserved across species, to the extent that rabbit muscle myosin II will bind to actin from an amoeba.

Missin' You
by: Trey Songz[Chorus]
I can't stop missin you.
Wish I was there with you.
I can't stop missin you.
No, no, no, no.
I can't stop missin you. (no)
Wish I was there with you. (with you)
I can't stop missin you.
No, no, no, no.
[Verse]
I miss the way you kiss,
miss the way you wear them heels and make it switch.
Miss the way your hair blows in the wind.
And I miss you stayin here 'til the mornin,
Miss the way you put on your makeup.
Miss the way you love me too much.
It's everything about you baby.
Wanna know where you been lately.
Do you go out?
Do you still live at your old house?
Do you got somebody new in your life?
Cuz I can't get you out of my mind.
[Pre-Chorus]
And I wanna erase,
but I can't stop seein' your face.
And every girl I try to replace you with.
Why can't I get over it?
Simply cuz I can't...
[Chorus]
I can't stop missin you. (can't stop)
Wish I was there with you. (with you)
I can't stop missin you.
No, no, no, no.
I can't stop missin you. (can't stop)
Wish I was there with you. (with you)
I can't stop missin you.
No, no, no, no.
I can't stop...
[Verse]
Missin everything you say,
missin all the crazy love we made.
Why'd you throw it all away?
I want you to know
It's been hell tryna do this without you here.
Baby, '07's supposed to be our year.
You confront my worst fears.
And I had my doubts,
every time you was going out.
Cuz I knew you were tellin me lies
and I can't get that outta my mind.
[Pre-Chorus]
And I wanna erase,
but I can't stop seein' your face.
And every girl I try to replace you with.
Why can't I get over it?
Simply cuz I can't...
[Chorus]
I can't stop missin you. (can't stop)
Wish I was there with you. (with you)
I can't stop missin you.
No, no, no, no.
I can't stop missin you. (can't stop)
Wish I was there with you. (with you)
I can't stop missin you.
No, no, no, no.
[Breakdown]
Wish I
Could wake up and forget about you.
Not try
to call you when I know I want to
(Oh WIsh I)
I gotta fight this feeling.
(Wish I)
Can't let it take over me.
(Wish I)
You just don't understand how much you were a part of me.
[Chorus x3]
I can't stop missin you.
Wish I was there with you. (with you)
I can't stop missin you.
No, no, no, no.
I can't stop missin you. (can't stop)
Wish I was there with you. (with you)
I can't stop missin you.
