Gene Expression + Phenotype

Homozygous null mice fail to survive past P1 and exhibit pallor, fetal growth retardation, impaired terminal differentiation of erythrocytes and granulocytes, a pale liver and reduced ossification of the long bones in the hindlimb. Mutant MEFs show impaired G0 arrest upon serum deprivation.
