The "C" sub-family of chemokine receptors contains only one member: XCR1, the receptor for XCL1 and XCL2 (or lymphotactin-1 and -2).
XCR1 is also known as GPR5.
The protein encoded by this gene is a chemokine receptor belonging to the G protein-coupled receptor superfamily. The family members are characterized by the presence of 7 transmembrane domains and numerous conserved amino acids. This receptor is most closely related to RBS11 and the MIP1-alpha/RANTES receptor. It transduces a signal by increasing the intracellular calcium ions level. The viral macrophage inflammatory protein-II is an antagonist of this receptor and blocks signaling. Two alternatively spliced transcript variants encoding the same protein have been found for this gene.[1]

Turbo-teen
by: Sugar HighIf you told the truth and lied too, anythin’
And If I ever touched your skin I’ll die, oh I
Could’ve said I want you or told you something true
If really wanted you I’ll lie
And I told you, everything’s fine…
Yeah that’s what I’d say, you’re firebird is most amazing
Turbo-oh-teen!
Now she’s at it again, I see her every weekend
Wish I had a dime for every time, oh I
Ca-Caught her again with a cigarette on the patio, with her hair still wet
She’s the girl with the rockin’ wholesome plans, oh I
Know her every time…
Yeah that’s what I’ll say, you’re firebird is most amazing
Turbo-oh-teen!
But I won’t mean it
Had girl just like you
I’d never say goodbye too now
Every girl’s just like you
Every girl just likes you
But it no better when it’s alright
It’s alright
