Cytosolic protein on membrane

Dear all,

I'm studying membrane proteins from human spermatozoa. We purified and
identified one of these proteins as "Triose Phosphate Isomerase". The
location of this protein was confirmed by electronic microscopy and is on
the acrosomic membrane. In literature, this protein is known as cytosolic.
My questions are: Do you have an idea by which mechanism this protein is
located on the membrane? Does anybody have a reasonable explanation for
that? Does anybody know a reference showing a cytosolic protein located in
membrane?
Thanks for all answers.

Luc CAMOIN
