Alkaline ceramidase 1 also known as ACER1 is a ceramidase enzyme which in humans is encoded by the ACER1 gene.[3]


ACER1 mediates cellular differentiation by controlling the generation of sphingosine (SPH) and sphingosine-1-phosphate (S1P).[3]

Model organisms[edit]

Model organisms have been used in the study of ACER1 function. A conditional knockout mouse line called Acer1tm1a(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute.[7] Male and female animals underwent a standardized phenotypic screen[4] to determine the effects of deletion.[8][9][10][11] Additional screens performed: - In-depth immunological phenotyping[5] - in-depth bone and cartilage phenotyping[6]
