Miscellaneousi

Miscellaneous

This protein is subject to phase-variable expression associated with alteration in the length of the CCAA repeat region. This mechanism is called slipped-strand mispairing. Addition or loss of CCAA repeat units would change the reading frame and result in introduction of stop codons downstream of the repeat region. This may be a mechanism of regulation and a way to avoid the immunological response of the host (By similarity).By similarity
