Ascomycota of their hosts. Owing to their long evolutionary history, the Ascomycota have evolved the capacity to break down almost every organic substance. Unlike most organisms, they are able to use their own enzymes to digest plant biopolymers such as cellulose or lignin. Collagen, an abundant structural protein in animals, and keratin—a protein that forms hair and nails—, can also serve as food sources. Unusual examples include "Aureobasidium pullulans", which feeds on wall paint, and the kerosene fungus "Amorphotheca resinae", which feeds on aircraft fuel (causing occasional problems for the airline industry), and may sometimes block fuel pipes.

Cleft lip and palate transmembrane protein 1 may belong to a new gene family. This family also contains the "Homo sapiens" cisplatin resistance related protein CRR9p which is associated with CDDP-induced apoptosis. Cleft lip and palate transmembrane protein 1 Cleft lip and palate transmembrane protein 1 is a protein that in humans is encoded by the "CLPTM1" gene. It belongs to a family of several eukaryotic cleft lip and palate transmembrane protein 1 sequences. Cleft lip with or without cleft palate is a common birth defect that is genetically complex. The nonsyndromic forms have been studied genetically using linkage and candidate-gene association studies with only partial success
