description: This family of proteins found in eukaryotes represents sperm acrosome-associated protein
  9 (SPACA9, previously known as C9orf9 or MAST). Sperm acrosome-associated protein 9 has been suggested
  to form a complex with calcium-binding proteins calreticulin and caldendrin localised to the acrosome.
  Despite this, no known protein interaction motifs have been identified in MAST/SPACA9 [[cite:PUB00080694]].
