The human gene Chromosome 3 open reading frame 14 is a gene of uncertain function located at 3p14.2 near fragile site FRBA3—which falls between this gene and the centromere. Its protein is expected to localize to the nucleus and bind DNA. Orthologs have been identified in all of the major animal groups, minus amphibians and insects, tracing as far back as the sea anemone; indicating an origin of over 1000 mya, highlighting its importance in the animal genome.
C9orf64 is a gene located on chromosome 9, that in humans encodes the protein queuosine salvage protein. The function and biological process of the queuosine salvage protein is a queuosine-nucleotide N-glycosylase/hydrolase (QNG1) that releases queuine from Q-5'-monophosphate, and this activity is required for the salvage of queuine from exogenous Queuosine by S. pombe and HeLa cells. Some evidence from orthologs indicates it may be involved in tRNA processing and recycling. The most common mRNA contains 4 coding exons, and it has 2 additional alternatively spliced exons. C9orf64 has been found in 5 different splice variants.
KIAA1704, also known as LSR7, is a protein that in humans is encoded by the GPALPP1 gene. The function of KIAA1704 is not yet well understood. KIAA1704 contains one domain of unknown function, DUF3752. The protein contains a conserved, uncharged, repeated motif GPALPP(GF) near the N terminus and an unusual, conserved, mixed charge throughout. It is predicted to be localized to the nucleus.
Chromosome 20 open reading frame 111, or C20orf111, is the hypothetical protein that in humans is encoded by the C20orf111 gene. C20orf111 is also known as Perit1, HSPC207, and dJ1183I21.1. It was originally located using genomic sequencing of chromosome 20. The National Center for Biotechnology Information, or NCBI, shows that it is located at q13.11 on chromosome 20, however the genome browser at the University of California-Santa Cruz (UCSC) website shows that it is at location q13.12, and within a million base pairs of the adenosine deaminase locus. It was also found to have an increase in expression in cells undergoing hydrogen peroxide(H
2O
2)-induced apoptosis. After analyzing the amino acid content of C20orf111, it was found to be rich in serine residues.
Uncharacterized LOC644249 gene., also known as RP11-195B21.3, is about 1058 base pairs long and is found in Homo sapiens on chromosome 9q12. More specifically, the sequence is located on Chromosome: 9; NC_000009.11(67977457..67987991 bp). This gene’s protein product is the “coiled-coil domain-containing protein 29” which is 291 amino acids long and may contain a conserved domain in the superfamily, pfam 12001. In particular, this conserved domain contains the domain of unknown function DUF3496 which is about 110 amino acids long, functionally uncharacterized, and found in eukaryotes. Other possible motifs for the protein product exist but the DUF3496 remains the most likely. This protein may play a role as a transmembrane protein.
Coiled coil domain containing protein 120 (CCDC120), also known as JM11 protein, is a protein that, in humans, is encoded by the CCDC120 gene. The function of CCDC120 has not been formally identified but structural components, conservation, and interactions can be identified computationally.
Coiled-coil domain-containing protein 144A is a protein that in humans is encoded by the CCDC144A gene. An alias of this gene is called KIAA0565. There are four members of the CCDC family: CCDC 144A, 144B, 144C and putative CCDC 144 N-terminal like proteins.
Protein FAM214A, also known as protein family with sequence similarity 214, A (FAM214A) is a protein that, in humans, is encoded by the FAM214A gene. FAM214A is a gene with unknown function found at the q21.2-q21.3 locus on Chromosome 15 (human). The protein product of this gene has two conserved domains, one of unknown function (DUF4210) and another one called Chromosome_Seg. Although the function of the FAM214A protein is uncharacterized, both DUF4210 and Chromosome_Seg have been predicted to play a role in chromosome segregation during meiosis.
Coiled-coil domain containing 94 (CCDC94) is a protein that in humans is encoded by the CCDC94 gene. The CCDC94 protein contains a coiled-coil domain, a domain of unknown function (DUF572), an uncharacterized conserved protein (COG5134), and lacks a transmembrane domain.

Coiled-coil domain 47 (CCDC47) is a gene located on human chromosome 17, specifically locus 17q23.3 which encodes for the protein CCDC47. The gene has several aliases including GK001 and MSTP041. The protein itself contains coiled-coil domains, the SEEEED superfamily, a domain of unknown function (DUF1682) and a transmembrane domain. The function of the protein is unknown, but it has been proposed that CCDC47 is involved in calcium ion homeostasis and the endoplasmic reticulum overload response.
GPATCH11 is a protein that in humans is encoded by the G-patch domain containing protein 11 gene.
