Protein attributes

Sequence length558 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Polymerase that creates the 3'-poly(A) tail of mRNA's. May acquire specificity through interaction with a cleavage and polyadenylation factor By similarity.

Catalytic activity

ATP + RNA(n) = diphosphate + RNA(n+1).

Cofactor

Binds 2 magnesium ions. Also active with manganese By similarity.

Subcellular location

Nucleus.

Miscellaneous

The C.albicans mating-type-like (MTL) locus contains, in addition to the genes for the regulatory proteins (MTLA1, MTLA2, MTLALPHA1 and MTLALPHA2), a and alpha idiomorphs of a phosphatidylinositol kinase (PIKA and PIKALPHA), a poly(A) polymerase (PAPA and PAPALPHA) and an oxysterol binding protein-like protein (OBPA and OBPALPHA).

Sequence similarities

Belongs to the poly(A) polymerase family.
