TMEM106A
TMEM106A je gen koji kod Homo sapiens kodira transmembranski protein 106A (TMEM106A).[5] Nalazi se na poziciji 17q21,31 plus lanca, pored gena povezanih sa rakom NBR1 i BRCA1.[5][6] Gen TMEM106A sadrži domen nepoznte funkcije, DUF1356.[5]
Struktura proteina
urediProtein TMEM106A ima molekulsku težinu od 28,9 kdal. Sadrži 262 aminokiseline, od kojih su 240 u domenu funkcije.[5] Protein ima tranmembransku regiju.[7] Postoje dokazi o sekundarnoj transmembranskoj regiji kod ljudi, ali nije konzerirana u srodnim ortolozima.[8] Protein ne sadrži proteinsle peptidne signale.[9] Njegova truktura sadrži sličan udio alfa-heliksa i beta-lanac sekundarnih struktura (što ne uključuje transmembranske strukture).[10][11]
Postoji nekoliko područja za posttranslacijske modifikacije za TMEM106A, ko što su:
- Aminokiselinska sekvenca
Dužina polipeptidnog lanca je 262 aminokiseline, a molekulska težina 28.920.[15].

Homologija
urediParalozi
urediGen TMEM106A ima dva paraloga: TMEM106B i TMEM106C. Ovi paralozi pripadaju porodici gena pfam07092, superporodice DUF1356. Ova porodica sastoji se od nekoliko sisarskih proteina, dužine oko 250 aminokiselina.[16] TMEM106B i TMEM106C konzervirani su, od beskičmenjakka do sisara.

Ortholozi
urediGen TMEM106A pronađen je samo u koljenu Chordata.[21] Od tri potkoljena, TMEM106A najčešće se nalazi u Vertebrata, a pronađen je i u odabranim članovima Tunicata, koji e hrane filteiranjem morske vode kao i beskičmenjaci. Ovo razdvajanje (pot)koljena dogodilo se prije 722,5 miliona godina.[22] TMEM106A nema kod bakteria, biljaka ii gljiva.

Ekspresija
urediTMEM106A se eksprimira u nekoliko ljudskih tkiva. Tkiva/organi s najvećom ekspresijom su maternica, bubrezi, tanko crijevo i želudac.[17][23] EST profili za ortologe pokazuju da je ekspresija konzervirana sa najvećom ekspresijom u bubrezima i manjom ekspresijom u nekoliko drugih područja. Neka tkiva nikada ne pokazuju ekspresiju, uključujući: mišiće, masno tkivo i kosti.
Gensko susjedstvo
urediU Homo sapiens, TMEM106A nalazi se pored NBR1, gena koji je identifikovan kao jajnički tumorski antigen nađen u raku jajnika.[24] It is also located near BRCA1, a breast cancer tumor suppressor gene.[25] Prvih 140 aminokiselina proteina TMEM106A, uključujući dijelove DUF1356 i transmembransku regiju, deletiraju se zajedno s BRCA1, tokom raka dojke s ranim početkom.[26]
