Transmembrane 210 (TMEM210)

[edit | edit source]

Transmembrane 210 (TMEM210) is a gene that encodes the TMEM210 protein.[1]

In humans (Homo sapiens), the TMEM210 gene is located on chromosome 9 at the cytogenetic band 9q34.3.[1]

Protein

[edit | edit source]

Isoforms

[edit | edit source]

No known isoforms.

MW/pI

[edit | edit source]

TMEM210 has a molecular average mass and mono-isotopic mass of 15.5k kDa.[2]

The theoretical isoelectric point (pI) is 4.13.[2]

Composition

[edit | edit source]

Compositional analysis of TMEM210 precursor protein sequence, computed via SAPS, indicates that leucine (16.3%), proline (12.2%), alanine (9.5%), and valine (9.5%) are the top four amino acids that compose the TMEM210 protein sequence.[3]

Motifs

[edit | edit source]

Utilizing MotifFinder, the five motifs were found in total. It indicated that there are two types of phosplhoketolase present and an acetyl-CoA synthase.[4] One phosplhoketolase (COG3957) was indicated to be a type utilized for carbohydrate transport and metabolism.[4] Whereas the acetyl-CoA synthase identified is used to form acetyl-CoA, which is important for glucose/fatty acid/cholesterol production.[4]

Homology

Paralogs

[edit | edit source]

No paralogs were found in humans. However in dogs (Canis lupus familiaris), the western lowland gorilla (Gorilla gorilla gorilla), panamanian white-face capuchin (Cebus imitator), eurasian badger (Mele meles), and large flying fox (Pteropus vampurus); paralogs in those species were found.

Orthologs

Multiple Sequence Alignment of TMEM210

[edit | edit source]

Alignment Sequence of Humans and 22 Mammal Orthologs

[edit | edit source]

A multiple sequence alignment was conducted analyzing the amino acid sequences of humans versus the 22 mammal orthologs (shown above).[5] It was shown that in frames 81 to 160, besides the methionine, amino acid, alanine and proline were 100% conserved in all sequences.[5][6] In frames 161 to 240: serine, alanine, tyrosine, cysteine, glycine, leucine, glutamic acid, isoleucine, valine, glutamine, and aspartic acid were 100% conserved.[5][6] An area of interest in this section is the conserved ALIAL and VVLA sequences as they are near one another, and are 100% conserved.[5][6] In frames 241 to 320, only glutamic acid and leucine are 100% conserved.[5][6]

Alignment Sequence of Humans and 11 Virus Xenologs

In this alignment, which analyzed the amino acid sequences of humans versus 11 virus xenologs: only leucine, glycine, and phenylalanine were 100% conserved; all 100% conserved amino acids were found between reading frame 1 and 80.[5] [6]

Interacting Proteins

[edit | edit source]

When mapping potential protein interactions with TMEM210, 10 possible proteins were identified (SMIM9, SMIM8, SCL25A41, TOMM20L, CBY2, SLC25A2, RASEF, PLCH1, THEMIS2, PDZD8).[8] However, the first 7 of that list are simply listed due to being part of a study that analyzed 12 genes related to the testis, which included TMEM210.[9] This knockout study found that all genes tested were not needed for male fertility as when they were knocked out, there was no impact.[9]

PLCH1, THEMIS2, PDZ8 and TMEM210 were included in a study that was trying to determine connections between higher maternal plasma glucose (PG) concentrations and genes.[10] PLCH1 and THEMIS2 was found to be associated with 1-h PG levels and gestational diabetes mellitus (GDM) levels. [10] TMEM210 was found to be associated with 1-h and 2-h PG levels.[10] PDZD8 was associated only for 1-h PG.[10]
