CSF-1

Factor estimulante de colonias Macrófagos (M-CSF) o también Colony stimulating factor 1 (CSF-1), es una citoquina secretada que induce a las células madre hemopoyéticas a diferenciarse a macrófago u otros tipos celulares relacionados. Las células eucarióticas también producen M-CSF para combatir infecciones virales intracelulares. M-CSF se une a su receptor, el Colony stimulating factor 1 receptor. Puede que el M-CSF también esté involucrado en el desarrollo de la placenta.

Estructura

Es una citoquina. La forma activa de la proteína se encuentra extracelularmente en forma de homodímero, estando unidos los monómeros por un enlace disulfuro. Se piensa que esta forma es producida a partir del procesamiento proteolítico de precursores unidos a membrana.

Se han encontrado cuatro variantes transcripcionales codificando tres isoformas diferentes.[1]

Se ha demostrado que MCSF interacciona con PIK3R2.[2]
