The present invention relates to polynucleotide and polypeptide molecules for
zacrp2, a novel member of the family of proteins bearing a collagen-like domain
and a C1q domain. The polypeptides and polynucleotides encoding them, are involved
in dimerization or oligomerization and may be used in the study thereof. The present
invention also includes antibodies to the zacrp2 polypeptides.
