repeating 5 amino acid motifs in proteins

I have sequenced a gene which is probably involved in the localization of  
glycolipids in a cyanobacterium.  It has very little homology to other
sequences in Genbank but it does have an interesting repeated amino acid
motif.  One segment of the protein has thirty-six degenerate repeats of 
five amino acids including a mostly conserved leucine position.  Does
anyone have any ideas about the potential function(s) of such repeats?
