Table I. CP is a moderately abundant cellular protein.

Values represent the mean percentage (± sd) of a particular ABP with respect to total protein. Number of samples is given in parentheses. Molar ratios of each ABP to total actin were determined by multiplying the percentage of protein by the ratio of molecular weights and normalizing to actin concentration.

Protein	Total Protein	ABP:ActinMolar Ratio
Actin	0.37 ± 0.02 (4)	—
CPA	0.0015 ± 0.0001 (8)	1:207
CPB	0.0013 ± 0.0002 (8)	1:196
