Functions of PTM Sites

Modified Location	Modified Residue	Modification	Function	Reference
104	K	Acetylation	Acetylation at Lys-104 prevents interaction with guanine nucleotide exchange factors (GEFs).	-
170	K	ubiquitylation	Ubiquitinated by the BCR(LZTR1) E3 ubiquitin ligase complex at Lys-170 in a non-degradative manner, leading to inhibit Ras signaling by decreasing Ras association with membranes.	-
