description: This family (previously DUF4542) represents the homologs of Sperm microtubule associated
  protein 1 (SPMAP1 also known as C17orf98). These proteins contain a conserved IPPYN sequence motif.
  The EM structure of sperm DMTs shows that SPMAP1 interacts directly with the tubulin lattice at the
  A-tubule seam (between protofilaments A09/A10) where outer dense fibers (ODFs) are connected to dynein-decorated
  doublet microtubules (DMTs) [[cite:PUB00151496]].
